Preparation of mixed carbonates proceeded in one step from ketones and aldehydes via treatment with NaBH4 in dimethyl or diethyl carbonate solvent at elevated temperatures. This is an efficient and convenient alternative to the traditional two-step sequence of carbonyl reduction to alcohol and subsequent carbonate formation by treatment with an alkyl chloroformate. 25 examples are presented from 49-92% yield
通过在碳酸二甲酯或二乙基溶剂中用NaBH4处理,从酮和醛中一步制备混合碳酸盐。这是对羰基还原为醇和随后通过用氯甲酸烷基酯处理的随后碳酸盐形成的传统两步序列的有效且方便的替代方法。从49-92%的收率提供了25个实例,突出了该反应的多功能性。
