Chiral Vanadyl Salen Complex Anchored on Supports as Recoverable Catalysts
for the Enantioselective Cyanosilylation of Aldehydes. Comparison Among Silica,
Single Wall Carbon Nanotube, Activated Carbon and Imidazolium Ion as Support. — Some heterogeneous chiral vanadyl complexes are prepared in order to test
their efficiency in enantioselective addition of Tms-CN to aldehydes. The complex (II)
gives best results which are comparable to those obtained with the homogeneous catalyst (Ia). — (BALEIZAO, C.; GIGANTE, B.; GARCIA*, H.; CORMA, A.;
