A BNAlP-heterocycle

Abstract

We report the [2+2]-cyclization reaction of a phosphaalumene with its lighter analog, an iminoborane, to give a species with a four-membered BNAlP-heterocycle with alternating Lewis basic and acidic centers in the ring. The reactivity of this heterocycle towards alkenes and alkynes is described, giving chain molecules and ring-expanded species.
