method for the synthesis of arylselenides and aryltellurides has been established based on the oxidative cross-coupling between diorganyl dichalcogenides and aryl boronic acids. With trichloroisocyanuric acid as an oxidant, the reaction proceeded smoothly to afford the desired products in 45–97% yields at ambient temperature. Three reaction reagents used in this method are stoichiometric and the oxidation
基于二有机二硫属元素化物和芳基硼酸之间的氧化交叉偶联,建立了一种无过渡金属合成芳基硒化物和芳基碲化物的方法。以三氯异氰尿酸为氧化剂,反应顺利进行,在室温下以 45-97% 的产率得到所需产物。该方法中使用的三种反应试剂都是化学计量的,氧化副产物异氰脲酸可以很容易地分离和回收。除了芳基硼酸,芳基三氟硼酸盐和芳基三羟基硼酸盐也能够进行这种转化。
