Abstract

Investigations on the catalytic behaviour of titanium complexes formed from Ti (OPr) and a variety of Schiff bases, mainly the binaphthyl derivatives 2, 2′-bis (3-R-5-R-2- hydroxybenzylideneamino)-1, 1′-binaphthyl, toward the asymmetric trimethylsilylcyanation of some aromatic and aliphatic aldehydes demonstrated that
