摘要
Reactions of [L2Rh(acac)] (L = alkene or phosphine) with B(2)cat(3) yield the zwitterionic complexes [L2Rh(eta(6)-catBcat)] and [(acac)Bcat] cleanly; [(dppm)Rh(eta(6)-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-beta-methylstyrene.
