An efficient method for synthesizing diaryl ketones via merging of oxidative cleavage of C–C double bonds and recombination of aromatic groups is developed with Et4NI (2.5 mol%) as the catalyst and NaIO4 as the oxidant. The control experiments provide valuable mechanistic insights into the formation of diaryl ketones, and suggest that NaIO4 serves as an epoxidation and nucleophilic deformylation reagent
以Et 4 NI(2.5 mol%)为催化剂,NaIO 4为氧化剂,开发了一种有效的方法,该方法通过合并C–C双键的氧化裂解和芳族基团的
重组来合成二芳基酮。对照实验为二芳基酮的形成提供了有价值的机理见解,并表明NaIO 4可作为环氧化和亲核去甲酰基化试剂。
