Abstract

Abstract Crossed aldol-type reactions of enol trimethylsilyl ethers with aldehydes and ketones are smooth when carried out with a catalytic amount of a rhodium complex, Rh 4 (CO) 12 or [Rh (COD)(DPPB)] X (X= PF 6 and ClO 4; COD= cycloocta-1, 5-diene, DPPB= 1, 4-bis (diphenylphosphino) butane), under neutral conditions. A suitable catalyst enables the isolation of three different types of aldol reaction product, β-trimethylsiloxy ketones, β- ...
