[摘要]：Derivatives, and Condensed Benzenoid Compounds) Section Titanium and vanadium salen complexes have been prepd. from C2- and C1-sym. acyclic diamines. All of the complexes catalyzed the asym. addn. of trimethylsilyl cyanide to benzaldehyde and the sense of asym. induction was detd. by the nature of the substituents. The vanadium complex of a valine-derived diamine gave good results with a range of arom. and aliph. aldehydes.
