Catalytic and solid state NMR spectroscopic study of bimetallic catalysts: synergisms between Lewis acid and transition metal sites in carbonylation and transfer hydrocyanation reactions KU Leuven
Catalytic coupling of two small molecules may proceed much faster if each molecule is activated on a discrete metal centre. Especially combinations of transition metals (TM) and Lewis acids (LA) can generate a special synergy in heterogeneous catalysis. In carbonylation of alcohols (or epoxides), CO and the alcohol (epoxide) are activated resp. by TM and LA sites; in transfer hydrocyanations, the slow steps are accelerated by binding of ...
