Catalyst-Free Oxidative [3+2] Cycloaddition of Phenols and Styrenes in the Presence of a 2,3-Dichloro-5,6-dicyano-1,4-benzoquinone/1,1,1,3,3,3-hexafluoropropan-2-ol System

A catalyst-free oxidative [3+2] cycloaddition of phenols and styrenes was developed with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone as the oxidant and 1,1,1,3,3,3-hexafluoropropan-2-ol as the solvent at room temperature. With this method, a broad range of dihydrobenzofurans were efficiently and quickly obtained from readily available phenols and styrenes.
以 2,3-二氯-5,6-二氰基-1,4-苯醌为氧化剂和 1,1,1,3,3,3 开发了苯酚和苯乙烯的无催化剂氧化 [3+2] 环加成反应-六氟丙-2-醇在室温下作为溶剂。使用这种方法,可以从容易获得的苯酚和苯乙烯中高效快速地获得范围广泛的二氢苯并呋喃。
