Bromine/lithium exchange was performed upon treatment of α-bromo-vinylic chalcogenides with butyllithium in hexane at room temperature to provide α-chalcogen-vinyllithium intermediates quantitatively. Addition of electrophiles to the lithiated compounds gave the corresponding functionalized vinylic chalcogenides in good yields with retention of configuration.
在室温下,将α-溴代乙烯类硫属化合物与正丁基锂在己烷中反应,进行溴锂交换,以定量提供α-硫属元素-乙烯基锂中间体。向锂化的化合物中加入亲电子试剂,可得到相应功能化的乙烯基硫属化合物,收率良好,并保持构型不变。
