B(C₆F₅)₃ initiates the Grob fragmentation of cyclohexa-2,5-dien-1-yl-substituted acyl chlorides into a low-molecular-weight arene, carbon monoxide and HCl. In the presence of π-basic substrates such as alkenes and alkynes, HCl is transferred stepwise to afford the corresponding hydrochlorination products. The overall reaction is a decarbonylative transfer hydrochlorination driven by aromatization and carbon-monoxide release.

基于 B(C6F5)3 引发的 Grob 裂解的烯烃和炔烃的脱羰转移氯化氢

B(C ₆ F ₅ ) ₃引发 cyclohexa-2,5-dien-1-yl-取代的酰氯的 Grob 裂解为低分子量芳烃、一氧化碳和 HCl。在 π 碱性底物（如烯烃和炔烃）存在下，逐步转移 HCl 以提供相应的氢氯化产物。整个反应是由芳构化和一氧化碳释放驱动的脱羰转移氢氯化反应。
