Four new heteroleptic Ni() complexes with general formula [Ni()(LL’)], L = 2-(methylene-1,1′-dithiolato)-5-phenylcyclohexane-1,3-dione (L1) and 2-(methylene-1,1′-dithiolato)-5,5′-dimethylcyclohexane-1,3-dione (L2); L’ = 1,2-bis(diphenylphosphino)ethane (dppe) and bis(diphenylphosphino)monosulfide methane (dppms) were synthesized and characterized by elemental anal. and spectroscopy (IR, UV-Vis, 1H, 13C{1H} and 31P{1H} NMR). All complexes 1-4 were characterized by PXRD and single crystal X-ray crystallog. The solid state mol. structures revealed distorted square planar geometry about the four-coordinate Ni(II) metal center together with rare Ni···H-C intra/intermol. anagostic interactions in axial positions. In these complexes supramol. structures were sustained by non-covalent C-H···O, C-O···H-O, C-H···π, C-H···π (NiCS2, chelate), π···π and H···H interactions. Their electrocatalytic properties were investigated for oxygen evolution reaction (OER) in which complex 2 showed the highest activity with 10 mA cm-2 at the potential of 1.58 V vs. In addition, complex 2 also exhibits an OER onset potential at 1.52 V vs.

Application In Synthesis of 1,2-Bis(diphenylphosphino)ethane. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene.

Five new heteroleptic complexes of Cu(I), Ag(I), and Ni(II) having formulas [Cu3(dtc)2(dppf)2]PF6 (Cu-I), [Cu3(dtc)2(dppe)2]PF6 (Cu-II), [Cu(PPh3)2(dtc)] (Cu-III), [Ag3(dtc)2(PPh3)2]NO3 (Ag-I), and [Ni(dtc)(dppf)]PF6 (Ni-I) (dtc = N-ethanol-N-methylferrocenyl-dithiocarbamate; dppf = 1,1′-bis(diphenylphosphino)ferrocene; dppe = 1,1′-bis(diphenylphosphino)ethane; PPh3 = tripheylphosphine) have been synthesized and characterized using elemental anal., Fourier-transform IR, multinuclear NMR, UV-Vis spectroscopy, and single-crystal X-ray diffraction. The single-crystal X-ray diffraction studies indicate that Ag-I forms a rare trinuclear cluster in which the geometry around the two silver centers Ag1 and Ag3 is distorted tetrahedral, whereas the third silver center Ag2 shows a distorted trigonal planar geometry. The Ni-I complex has a distorted square-planar geometry around the Ni center. In addition, a side product [Ag2{S2(dppf)2}] (Ag-II) was obtained during an attempt to synthesize [Ag(dppf)(dtc)], where the two Ag centers are bridged by two sulfido centers and coordinated with two phosphorus centers of the dppf ligand to give rise to a distorted tetrahedral geometry. The solid-state structures of Ag-I, Ni-I, and Ag-II are stabilized by a variety of weak interactions. The nature of these interactions has been addressed with the help of Hirshfeld surface analyses. In addition, the weak argentophilic interaction in Ag-I and Ag-II have been studied using quantum theory of atoms in mols. and natural bond orbital calculations The electrochem. properties of the complexes have been investigated using cyclic voltammetry, where Cu-I and Cu-II exhibited two quasi-reversible waves, whereas Cu-III, Ag-I, Ag-II, and Ni-I exhibited only one quasi-reversible peak.

Reference of 1,2-Bis(diphenylphosphino)ethane. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: 1,2-Bis(diphenylphosphino)ethane, is researched, Molecular C26H24P2, CAS is 1663-45-2, about Ranking Ligands by Their Ability to Ease (C6F5)2Ni(II)L → Ni0L + (C6F5)2 Coupling versus Hydrolysis: Outstanding Activity of PEWO Ligands. Author is Ponce-de-Leon, Jaime; Gioria, Estefania; Martinez-Ilarduya, Jesus M.; Espinet, Pablo.

The NiII literature complex cis-[Ni(C6F5)2(THF)2] is a synthon of cis-Ni(C6F5)2 that allows the authors to establish a protocol to measure and compare the ligand effect on the Ni(II) → Ni(0) reductive elimination step (coupling), often critical in catalytic processes. Several ligands of different types were submitted to this Ni-meter comparison: bipyridines, chelating diphosphines, monodentate phosphines, PR2(biaryl) phosphines, and PEWO ligands (phosphines with one potentially chelate electron-withdrawing olefin). Extremely different C6F5-C6F5 coupling rates, ranging from totally inactive (producing stable complexes at room temperature) to those inducing almost instantaneous coupling at 25°, were found for the different ligands tested. The PR2(biaryl) ligands, very efficient for coupling in Pd, are slow and inefficient in Ni, and the reason for this difference was examined In contrast, PEWO type ligands are amazingly efficient and provide the lowest coupling barriers ever observed for NiII complexes; they yield up to 96% C6F5-C6F5 coupling in 5 min at 25° (the rest is C6F5H) and 100% coupling with no hydrolysis in 8 h at -22 to -53°. The ability of ligands to facilitate a difficult C-C coupling and protect from hydrolysis in Ni(II) is very different from their performance in Pd(II). Most remarkably, PR2(biaryl) ligands with very good performance in Pd(II) are not efficient in Ni(II), whereas PEWO ligands are amazingly efficient and induce C6F5-C6F5 coupling even at -50°.

After consulting a lot of data, we found that this compound(1663-45-2)Reference of 1,2-Bis(diphenylphosphino)ethane can be used in many types of reactions. And in most cases, this compound has more advantages.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 1,2-Bis(diphenylphosphino)ethane(SMILESS: P(CCP(C1=CC=CC=C1)C2=CC=CC=C2)(C3=CC=CC=C3)C4=CC=CC=C4,cas:1663-45-2) is researched.SDS of cas: 65705-44-4.

Let’s take a look at the latest research on this compound (cas:1663-45-2).

A family of stable anticancer gold(III)-based therapeutic complexes containing cyclometalated triphenylphosphine sulfide ligands have been prepared The anticancer properties of the newly developed complexes [AuCl2{κ2-2-C6H4P(S)Ph2}] (1), [Au(κ2-S2CNEt2){κ2-2-C6H4P(S)Ph2}]PF6 (2), [AuCl(dppe){κC-2-C6H4P(S)Ph2}]Cl (3), and [Au(dppe){κ2-2-C6H4P(S)Ph2}][PF6]2 (4) were investigated toward five human cancer cell lines [cervical (HeLa), lung (A549), prostate (PC3), fibrosarcoma (HT1080), and breast (MDA-MB-231)]. In vitro cytotoxicity studies revealed that compounds 2-4 displayed potent cell growth inhibition (IC50 values in the range of 0.17-2.50 μM), comparable to, or better than, clin. used cisplatin (0.63-6.35 μM). Preliminary mechanistic studies using HeLa cells indicate that the cytotoxic effects of the compounds involve apoptosis induction through ROS accumulation. Compound 2 also demonstrated significant inhibition of endothelial cell migration and tube formation in the angiogenesis process. Evaluation of the in vivo antitumor activity of compound 2(I) in nude mice bearing cervical cancer cell (HeLa) xenografts indicated significant tumor growth inhibition (55%) with 1 mg/kg dose (every 3 days) compared with the same dose of cisplatin (28%).

To investigate the influence of the coordination geometry on the magnetization relaxation dynamics, two geometric isomers of a five-coordinate low-spin Co(II) complex with the general mol. formula [Co(DPPE)2Cl]SnCl3 (DPPE = diphenylphosphinoethane) were synthesized and structurally characterized. While one isomer has a square pyramidal geometry (Co-SP (1)), the other isomer figures a trigonal bipyramidal geometry (Co-TBP (2)). Both complexes were already reported elsewhere. The spin state of these complexes is unambiguously determined by detailed d.c. (dc) magnetic data, X-band, and high-frequency EPR measurements. Slow relaxation of magnetization is commonly observed for systems with S > 1/2. However, both 1 and 2 show field-induced slow relaxation of magnetization. Especially 1 shows relaxation times up to τ = 35 ms at T = 1.8 K, which is much longer than the reported values for undiluted Co(II) low-spin monomers. In 2, the maximal field-induced relaxation time is suppressed to τ = 5 ms. We attribute this to the change in g-anisotropy, which is, in turn, correlated to the spatial arrangement of ligands (i.e., coordination geometry) around the Co(II) ions. Besides the detailed electronic structure of these complexes, the exptl. observations are further corroborated by theor. calculations

Author is Feng, Xuanyu; Pi, Yunhong; Song, Yang; Brzezinski, Carter; Xu, Ziwan; Li, Zhong; Lin, Wenbin.

We report here the design of two multifunctional metal-organic frameworks (MOFs), mPT-Cu/Co and mPT-Cu/Re, comprising cuprous photosensitizers (Cu-PSs) and mol. Co or Re catalysts for photocatalytic hydrogen evolution (HER) and CO2 reduction (CO2RR), resp. Hierarchical organization of Cu-PSs and Co/Re catalysts in these MOFs facilitates multielectron transfer to drive HER and CO2RR under visible light with an HER turnover number (TON) of 18700 for mPT-Cu/Co and a CO2RR TON of 1328 for mPT-Cu/Re, which represent a 95-fold enhancement over their homogeneous controls. Photophys. and electrochem. investigations revealed the reductive quenching pathway in HER and CO2RR catalytic cycles and attributed the significantly improved performances of MOFs over their homogeneous counterparts to enhanced electron transfer due to close proximity between Cu-PSs and active catalysts and stabilization of Cu-PSs and mol. catalysts by the MOF framework.
