摘要：

Copper(II) triflate catalyzes the ring-opening of aryl- and vinyl-substituted epoxides with various carbonyl compounds to furnish 1,3-dioxolanes under mild conditions. Alkyl- and alkoxy-carbonyl-substituted epoxides remain unchanged under reaction conditions. This allows selective opening of aryl-substituted epoxides in the presence of alkyl-substituted ones.
