B(C6F5)3‐Catalyzed Ring Opening and Isomerization of Unactivated Cyclopropanes

Abstract Catalytic amounts of B(C 6 F 5 ) 3 promote the ring opening and subsequent isomerization of a series of unactivated cyclopropanes to afford terminal olefins in good yields when a hydrosilane and 2,6‐dibromopyridine are employed as additives.
