An atom-economical method for radical (phenylsulfonyl)difluoromethylation of isocyanides with PhSOCFH under transition-metal-free conditions has been developed. A PhSOCF radical is generated through the oxidation of PhSOCF after the deprotonation of PhSOCFH in one pot. The reaction exhibits excellent functional-group tolerance and the resulting products can be further modified with the removal of a PhSO group to give other CF-containing compounds.
发展了一种在无过渡金属条件下通过异氰化物的自由基(苯磺酰基)二氟甲基化的原子经济性方法。PhSOCFH 在脱质子后,通过 PhSOCF 的氧化生成 PhSOCF 自由基。该反应表现出优异的官能团容忍性,并且所得产物可以通过去除 PhSO 基团进一步修饰,得到其他含 CF 的化合物。
