1,2-diphenylethylenediamine linked chiral Ti(IV) complex--a new entry to the highly enantioselective silylcyanation of aliphatic and aromatic aldehydes.

Highly enantioselective silylcyanation of aliphatic and aromatic aldehydes was achieved by using a 1,2-diphenylethylenediamine linked chiral Ti(IV) complex as the catalyst.
