cascade reaction of aryl alkynoates has been developed with thiol as a coupling partner. This radical process has been demonstrated to proceed through S–H bond cleavage, thiolation of alkynoate, aryl migration, and decarboxylation. This reaction tolerates a wide scope of substrates resulting in good chemical yields, which provides an easy and practical strategy for preparation of trisubstituted vinyl
已经开发了硫醇引发的烷基炔基芳烃的级联反应,其中硫醇为偶联配偶体。已经证明该自由基过程是通过S–H键断裂,炔酸硫醇化,芳基迁移和脱羧进行的。该反应可耐受各种各样的底物,从而产生良好的化学收率,这为制备三取代的乙烯基硫化物提供了简便实用的策略。
