Abstract

Reactions of [L2Rh(acac)] (L = alkene or phosphine) with B2cat3 yield the zwitterionic complexes [L2Rh(η6-catBcat)] and [(acac)Bcat] cleanly; [(dppm)Rh(η6-catBcat)], the X-ray structure of which is reported, is an excellent catalyst for the diboration of vinylarenes and unstrained internal alkenes cis- and trans-stilbene and trans-β-methylstyrene.
