Linear and macrocyclic oligo(p-phenylene iminoboranes) with ferrocenyl side groups – observation of selective, non-templated macrocyclization

Abstract

A series of linear oligo(p-phenylene iminoboranes), which are BN-modified congeners of oligo(p-phenylene vinylenes), featuring pendent ferrocene groups have been prepared. Stoichiometric reaction of a bis-silylamine with a bisborane led to selective formation of an unprecedented macrocycle, without the use of a template.
