Abstract

The efficient and chemoselective preparation of acetals and ketals from carbonyl compounds, transacetalization reactions, the conversion of epoxides to acetonides, and the preparation of acylals from aldehydes in the presence of catalytic amounts of 2, 4, 4, 6- tetrabromo-2, 5-cyclohexadienone (TABCO) are described.
