Alkenyl-substituted benzothiophenes were prepared by the first Heck reactions of 2,3-di- and 2,3,6-tribromobenzothiophene. Functionalized dibenzothiophenes were prepared based on domino ‘twofold Heck-6Ï-electrocyclization’ reactions.
通过对2,3-二
溴和2,3,6-三
溴苯并噻吩进行第一次赫克反应,制备了烯烃基取代的
苯并噻吩。基于双重“赫克-6π-电环化”反应,制备了功能化的
二苯并噻吩。
