An esterification and amination of benzylic C–H bonds was developed by using 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) under metal- and iodide-free conditions. Both carboxylic acids and amines could be used as ideal coupling partners for the oxidative coupling reactions with various diarylmethanes. A close to equal amount of coupling reagents was enough to afford the product in good to high yields
在不含金属和碘化物的条件下,使用 2,3-二氯-5,6-二氰基-1,4-苯醌 (DDQ) 开发了苄基 C-H 键的酯化和胺化。羧酸和胺均可用作与各种二芳基甲烷进行氧化偶联反应的理想偶联伙伴。接近等量的偶联试剂足以以良好至高产率提供产物。
