A study has been made of the asymmetric hydrosilylation of acetophenone by diphenylsilane under the influence of rhodium complexes with chiral phosphites. The enantioselective nature of the reaction depends on the phosphite structure, the acetophenon

Enantioselective catalysis by metal complexes. 5. Asymmetric hydrosilylation using the phosphine complex [Rh(COD)Cl]2/(S)-Phephos

Autor: Yu. D. Koreshkov, E. I. Klabunovskii, E. Yu. Zhorov, V. A. Pavlov

Publikováno v: Bulletin of the Academy of Sciences of the USSR Division of Chemical Science. 39:1771-1774

The complex [Rh(COD)Cl]2/(S)-Phephos is demonstrated to be highly active and enantioselective in model hydrosilylation of acetophenone by diphenylsilane. The enantioselectivity increases as the reaction temperature increases. This allows the reaction

Relationship between product configuration and complex conformation in asymmetric catalysis on metal complexes (cross-coupling and hydrosilylation reactions)

Autor: V. A. Pavlov, A. A. Voloboev, E. I. Klabunovskii, E. Yu. Zhorov

Publikováno v: Journal of Molecular Catalysis. 59:119-135

In asymmetric cross-coupling and hydrosilylation reactions, as well as in asymmetric hydrogenation, under the action of chiral bis(diphenyl-phosphine) metal complexes having C 2 symmetry axis of the chelate ring, simple stereochemical rules define th

Rhodium aminophosphine chelate complexes as catalysts for asymmetric hydrosilylation

Autor: L. S. Gorshkova, K. N. Gavrilov, E. I. Klabunovskii, E. Yu. Zhorov, V. A. Pavlov
