The reaction of racemic (2-iodoferrocenyl)methanol with internal alkynes in the presence of (dppf)PdCl2 and i-Pr2NH produces alkenyl-substituted ferrocene carboxaldehydes in moderate yields. All reactions are carried out at 100 or 120 C for different reaction times (between 6 and 26 h) in a screw-cap Pyrex bottle. The scope and limitations of this reaction are studied by employing variously substituted 11 internal alkynes. The reactions are regioselective with alkynes having a sterically crowded substituent such as t-butyl and trimethylsilyl groups. Moreover, racemic 1-(2-iodoferrocenyl)ethanol derivatives are synthesized as two diastereomers. Both diastereomers are reacted with internal alkynes in the presence of (dppf)PdCl2 and i-Pr2NH at 120 C to afford alkenyl-substituted acetylferrocenes and ferroceno-pyrans in moderate to good yields. According to the alkyne employed, different reaction times (between 6 and 55 h) are necessary to drive the reactions to completion. Mechanisms are also suggested for the formation of observed products.

The catalyzed pathway has a lower Ea, but the net change in energy that results from the reaction is not affected by the presence of a catalyst. category: chiral-nitrogen-ligands, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 31886-57-4, in my other articles.

Upon incorporation of a noncovalent ion pair interaction, a new chiral ferrocenyl bisphosphorus ligand t-Bu-Wudaphos was developed. t-Bu-Wudaphos can be easily synthesized with very high diastereoselectivity as a highly air stable solid. The new ligand exhibited excellent reactivities and enantioselectivities in the asymmetric hydrogenation of alpha-methylene-gamma-keto-carboxylic acids via an ion pair noncovalent interaction (up to >99% conversion, >99% ee).

The new Me2Si-bridged [1]ferrocenophane ([1]FCP) with one iPr group in alpha position on a Cp ring was synthesized in an enantiopure (Sp-4) and a racemic form (rac-4). The molecular structure of rac-4 was determined by single-crystal X-ray analysis (tilt angle alpha = 20.15(14)). Experimental and calculated molecular structures of the related [1]FCPs with one (Sp-4 and rac-4) or two iPr groups (Sp,Sp-4) are compared to that of the nonsubstituted [1]FCP Me2Sifc. Differential scanning calorimetry (DSC) measurements resulted in HROP of 72(±2) kJ mol-1 for rac-4 and 62(±2) kJ mol-1 for the known Sp,Sp-4. While thermal ring-opening polymerization of Sp,Sp-4 gave insoluble material, the monosubstituted monomers Sp-4 and rac-4 resulted in soluble polymers with molecular weights (Mw) of 5.3 × 106 and 2.6 × 106 Da, respectively. Investigation of the polymer structures by 29Si NMR spectroscopy gave further evidence that the breakage of Si-Cp bonds occurs in the thermal ROP process of sila[1]ferrocenophanes.

Ferrocenyl diphosphines R2PF-P(R?)2 are effective, tunable ligands for the iridium catalyzed enantioselective hydrogenation of N-aryl imines in the presence of iodide and acid promoters. Structure-activity/selectivity correlations were found for the hydrogenation of N-(2-ethyl-6-methylphenyl)-N-(1?-methoxymethyl)-ethylidene-amine (MEA-imine) and for 2,3,3-trimethylindolenine (TMI). Extremely high catalytic activity and moderate to good enantioselectivity were observed for the MEA imine using a catalyst generated in situ from [Ir(cod)Cl]2 and (R)-(S)-PPF-P(3,5-Xyl)2 (xyliphos). With the same type of catalysts, several other N-aryl imines can be hydrogenated with enantioselectivities between 31 and 96%, albeit with lower catalyst activities.

The effect of an electric field on the adsorption of oligopeptides and DNA on a ferromagnetic substrate magnetized perpendicular to the surface was investigated. The direction of the magnetic moment of the substrate defines different adsorption rates for different enantiomers, and the direction of the electric field, perpendicular to the surface, defines different adsorption rates depending on the direction of the dipole moment of the adsorbed molecules.

Synthesis and electrochemical properties of mono- And (±)-l,2-dia!kylferrocenes and alkylferrocenium hexafluorophosphates in aqueous and micellar media

Simple methods have been developed for the preparation of a series of n-alkylferrocenes H(CH2)Fc (n = 3, 5-8, or 12) based on Friedel-Crafts acylation of ferrocenes followed by reduction of the corresponding ketones with Zn amalgam. The properties of H(CH2>nFc and the corresponding ferrocenium ions in micellar aqueous solutions and the behavior of watersoluble cations H(CH2)nFc+ in the absence of micelles were studied by cyclic voltammetry. In all cases, the formal redox potentials of ferrocenes (£ ‘) increase linearly as n increases up to 8. Whether micelles are present or not, the corresponding correlation equation has the following form: £”‘= a + pn, where beta= 29 mV in all cases. The synthesis of (±)-l-ethyI-2methylferrocene from racemic a-dimethylaminoethylferrocene is reported.
