Treatment of the bromobicyclo[1.1.0]butanes (=4)(=a) - (=c) with LDA led to the formation of the 1,2,3-butatrienes (=6) which were isomerized by excess base to the alkynes (=8). Reaction of [1-12-C](=4)(=c) with LDA afforded [3-12-C](=8)(=d), indicating that bicyclo[1.1.0]but-1(3)-ene (=5) was not an intermediate.
用LDA处理溴代双环[1.1.0]丁烷(= 4)(= a)-(= c)导致形成1,2,3-丁二烯(= 6),后者被过量的碱异构化成苯甲基。炔烃(= 8)。[1- 12 -C](= 4)(= c)与LDA的反应得到[3- 12 -C](= 8)(= d),表明双环[1.1.0] but-1(3) -ene(= 5)不是中间体。
