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 alkoxycarbonyl-substituted epoxides remainunchanged under reaction conditions. This allows selective opening of aryl-substituted epoxides in the presence of alkyl-substituted ones.
三氟甲磺酸铜 (II) 催化芳基和乙烯基取代的环氧化物与各种羰基化合物的开环,在温和条件下提供 1,3-二氧戊环。烷基和烷氧基羰基取代的环氧化物在反应条件下保持不变。这允许在烷基取代的环氧化物存在下选择性地打开芳基取代的环氧化物。
