Abstract

In the presence of a catalytic amount of [Rh (COD) Cl] 2, di-μ-chloro-bis (1, 5- cyclooctadiene) dirhodium, trimethylsilyl cyanide smoothly reacts with acetals derived from aliphatic, unsaturated and aromatic aldehydes to form the corresponding α-cyano derivatives in high yields. In the coexistence of catalytic amounts of [Rh (COD) Cl] 2 and trimethylsilyl cyanide, silyl enol ethers also react with acetals to yield the corresponding ...
