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

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.

Automated summary

In this study, various linear oligo(p-phenylene iminoboranes) with pendent ferrocene groups were synthesized from oligo(p-phenylene vinylenes) by BN modification. The formation of the unprecedented macrocycle was achieved through a stoichiometric reaction of bis-silylamine with a bisborane, without the need for a template.
