Make and break: Stronglyelectrophilicboranes RB(C6F5)2 (R=Me, CH2CH2Ph) react with an aminodihydropentalene substrate by CC bondcleavage with concomitant borylene insertion to yield the ring‐enlarged zwitterionic borate/iminium product.
产生和破坏:强亲电子的硼烷RB(C 6 F 5)2(R = Me,CH 2 CH 2 Ph)通过CC键断裂与伴随的亚芳基插入而与氨基二氢戊烯底物反应生成环扩大的两性离子硼酸酯/亚胺盐产品。
