Structurally diverse aldehydes are successfully converted into 1,1-diacetates with acetic anhydride using cyanuric chloride as a mild, convenient and inexpensive catalyst under solvent-free conditions. The noteworthy features of the present system are shorter reaction times, and mild and solvent-free conditions. Furthermore, it offers chemoselective protection of aldehydes.
在无溶剂条件下,使用三聚氯氰作为温和、方便且廉价的催化剂,可以将结构多样的醛与乙酸酐成功转化为 1,1-二乙酸酯。本系统的显着特点是反应时间更短,条件温和且无溶剂。此外,它还提供醛的化学选择性保护。
