In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Carbonylation of organic halo derivatives into acids in the presence of palladium complexes, published in 1982-06-30, which mentions a compound: 3411-48-1, Name is Tri(naphthalen-1-yl)phosphine, Molecular C30H21P, SDS of cas: 3411-48-1.

The reactions of organic halides with CO to give carboxylic acids were catalyzed by the reaction products of (PhCN)2PdCl2 (I) with different ligands, e.g., phosphines, stilbines, sulfides, and quinone. Tertiary phosphines, especially Ph3P, were the most effective ligands. The activity of the halides increased in the following orders: alkyl < Ph < benzyl and Cl < Br < I. With Ph3P and I the optimal P/Pd ratio was 4-6. After consulting a lot of data, we found that this compound(3411-48-1)SDS of cas: 3411-48-1 can be used in many types of reactions. And in most cases, this compound has more advantages.

Electric Literature of C30H21P. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: Tri(naphthalen-1-yl)phosphine, is researched, Molecular C30H21P, CAS is 3411-48-1, about Mechanistic Investigations of Reactions of the Frustrated Lewis Pairs (Triarylphosphines/B(C6F5)3) with Michael Acceptors. Author is Dupre, Jonathan; Gaumont, Annie-Claude; Lakhdar, Sami.

Frustrated Lewis pair (FLP)-catalyzed reduction of Michael acceptors is a challenging reaction that proceeds with specific FLP structures. Kinetics and equilibrium of the reactions of two phosphines (Ar3P), namely tri(1-naphthyl)phosphine and tri(o-tolyl)phosphine, are reported with reference electrophiles. The reason for the failure of the FLPs (Ar3P/B(C6F5)3) to reduce activated alkenes under H2 pressure is shown to be a hydrophosphination process that inhibits the reduction reaction. Kinetic and thermodn. factors controlling both pathways are discussed in light of Mayr’s free linear energy relationships.

Computed Properties of C30H21P. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: Tri(naphthalen-1-yl)phosphine, is researched, Molecular C30H21P, CAS is 3411-48-1, about Selective hydroformylation of 1-hexene to branched aldehydes using rhodium complex of modified bulky phosphine and phosphite ligands.

The selective hydroformylation of 1-hexene to branched aldehydes was investigated using rhodium complex of tri-1-naphthylphosphine PNp3 and tri-1-naphthylphosphite P(ONp)3. The PNp3 and P(ONp)3 ligands having more steric nature than PPh3 enhanced the formation of branched aldehydes at 110 °C and 4.0 MPa syngas pressure. The branched aldehyde selectivity increased remarkably (82%) by adding P(ONp)3 as auxiliary ligand in Rh/PNp3 catalyzed hydroformylation of 1-hexene. The high selectivity for the branched aldehydes is due to rapid alkene isomerization producing internal alkenes followed by hydroformylation to yield branched aldehydes.

Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 3411-48-1, is researched, SMILESS is C1=CC2=C(C=C1)C(=CC=C2)P(C1=CC=CC2=C1C=CC=C2)C1=CC=CC2=C1C=CC=C2, Molecular C30H21PJournal, Marine Chemistry called Characterization of minerals and organic phosphorus species in marine sediments using soft x-ray fluorescence spectromicroscopy, Author is Brandes, Jay A.; Ingall, Ellery; Paterson, David, the main research direction is mineral organic phosphorus species marine sediment; soft Xray fluorescence spectromicroscopy.Synthetic Route of C30H21P.

Phosphorus Near Edge X-ray Fluorescence Spectroscopy (P-NEXFS) data were collected on phosphorus containing phases including organic and inorganic compounds and minerals. Although phases containing P in the plus five oxidation state P(V) in a tetrahedral PO4 structure have similar primary fluorescence peak positions, the size, shape, and positions of secondary spectral features are diagnostic for different compounds and minerals. In particular, Ca phosphates exhibited a notable post-peak shoulder at 2154.5 eV, while oxidized iron phosphates had a distinctive pre-peak feature at 2148 eV. Polyphosphates have a broad secondary peak located ∼2 eV higher in energy than a similar feature in phosphate esters and diesters. Compounds containing P(V) in structures other than PO4 tetrahedra such as phosphonates have a primary peak shifted ∼1 eV lower than corresponding organo-phosphates. Organo-phosphates with P in the plus 3 oxidation state P(III) such as phosphines had primary fluorescence peaks shifted still further down in energy (2-3 eV). The substitution of aromatic C groups in close proximity to P structures in organic compounds generated both pre- and post-peak features as well as a number of secondary peaks. X-ray fluorescence mapping of P, Si, Al, Mg, and Na was conducted on a marine sediment sample with sub-micron spatial resolution Phosphorus was heterogeneously distributed in the sample and not correlated on a broad scale with any other element examined Much of the P present in the sample was located in small, 0.6-8 μm size, P-rich domains. Several P-rich regions were examined with P-NEXFS using a focused beam with 60 nm resolution and were found to consist of either calcium phosphate or polyphosphate phases. The presence of significant polyphosphate-dominated regions in a marine sediment sample supports the recent observations that such phases can play an important role in marine P cycling. The combination of fluorescence mapping and P-NEXFS data collection on fine particles provides a powerful new tool for environmental phosphorus studies.

After consulting a lot of data, we found that this compound(3411-48-1)Synthetic Route of C30H21P can be used in many types of reactions. And in most cases, this compound has more advantages.

A series of 73 bisphosphonium salts [R1R2R3P+(CH2)n-1,4-C6H4-L-1,4-C6H4(CH2)nP+R1R2R3]X2 and 10 monophosphonium salt derivatives [Ph-L-1,4-C6H4CH2PR1R2R3]Br, [4-MeC6H4CH2P+Ph3]X (R1-R3 = alkyl, Ph, substituted Ph, 2-thienyl, 2-furyl, 1-naphthyl; L = CO, CH2, O, SO2, NAc; X = Cl, Br) were synthesized and tested in vitro against several wild type and resistant lines of Trypanosoma brucei (T. b. rhodesiense STIB900, T. b. brucei strain 427, TbAT1-KO, and TbB48). More than half of the compounds tested showed a submicromolar EC50 against these parasites. The compounds did not display any cross-resistance to existing diamidine therapies, such as pentamidine. In most cases, the compounds displayed a good selectivity index vs. human cell lines. None of the known T. b. brucei drug transporters were required for trypanocidal activity, although some of the bisphosphonium compounds inhibited the low affinity pentamidine transporter. It was found that phosphonium drugs act slowly to clear a trypanosome population but that only a short exposure time is needed for irreversible damage to the cells. A comparative mol. field anal. model (CoMFA) was generated to gain insights into the SAR of this class of compounds, identifying key features for trypanocidal activity.

The 31P NMR data of non-quaternary (8-dimethylamino-naphth-1-yl)phosphonium salts, with emphasis on the 1J(31P, 1H) coupling constants, where scrutinized for their potential to yield information about N-P dative interactions. As for δ(29Si) and 1J(29Si, 1H) in the isosteric silanes, the data do not permit conclusions in favor of such interactions. 1J(31P, 1 H) of bis(8-dimethylaminonaphthalen-l-yl)phosphine in conjunction with the distances d(N···P) invalidates the basic assumption on which the claim of dative N→P/Si bonding in such phosphorus and silicon compounds rests, viz. that N···P/Si distances of ca. 270 pm are evidence for P/Si-hypercoordination. No evidence for hydrogen bonds N···H-P was found.

Author is Reetz, Manfred T.; Guo, Hongchao.

The concept of using mixtures of monodentate ligands in a combinatorial manner in order to influence enantio- or regioselectivity of transition metal catalyzed processes has been extended to include diastereoselectivity. Accordingly, 1,2- and 1,3-asym. induction in the Rh-catalyzed hydrogenation of a chiral allylic alc. and a chiral homo-allylic alc. has been studied by using mixtures of monodentate P-ligands. It was found that appropriate 1:1 mixtures of two different P-ligands enhance the degree of diastereoselectivity relative to the use of the resp. pure ligands themselves. Here, as in the previous cases regarding enantio- or regioselectivity, this type of combinatorial catalysis led to improved catalytic profiles without the need to prepare ligands.
