摘要：

A variety of carbonyl compounds can be easily converted to the corresponding 1,3-oxathiolanes in the presence of a catalytic amount of tantalum(V) chloride [TaCl5] on silica gel in dichloromethane. Mild reaction conditions, efficiency, high yields, operational simplicity, and only 2.5 mol% of TaCl5 catalyst are some of the major advantages of the procedure.
