Abstract
the use of silica supported tetrabutylammonium fluoride (TBAF-SiO2) as a non hygroscopic catalyst for silylating ketones and aldehydes with ethyltrimethylsilylacetate (ETSA) gives predominantly kinetic and Z silylenolethere at room temperature. TBAF-SiO2/ETSA is also useful in the silylation of alcohols.
