Abstract

It has been found that the hydrogenation kinetics of PhCOCOPh is first order in the cobalt complex and substrate. It has also been observed that the optical yield of the asymmetric hydrogenation of benzil depends on the pKa of amines. Mechanism involving complexation of benzil by amines (in solution) is postulated

Abstract

Найдено, что реакция гидрирования PhCOCOPh имеет первый порядок по комплексу кобальта и по субстрату. Показано, что оптический выход ассимметричного гидрирования бензипа зависти от значеия pKa аминов. Предложен механизм, предполагающий образования комплекса бензила с амином (в растворэ).
