A series of arylallenes react with HB(C F ) in a 2:1 molar ratio to give the tail-to-tail 1,6-diaryl-2-boryl-hexa-1,5-diene coupling products. The reaction of the phenylallene substrate with HB(C F ) was shown to initially give the 2-boryl-3,4-diphenyl-1,5-hexadiene head-to-head coupling product which then rearranged, by a thermally induced Cope rearrangement, into the final product.
一系列芳基丙二烯与HB(C₆F₅)₃以2:1的摩尔比反应，生成尾对尾的1,6 - 二芳基 - 2 - 硼基 - 己 - 1,5 - 二烯偶联产物。苯基丙二烯底物与HB(C₆F₅)₃的反应最初生成2 - 硼基 - 3,4 - 二苯基 - 1,5 - 己二烯头对头偶联产物，然后通过热诱导的科普重排重排为最终产物。
