[L2Rh(acac)]（L = 烯烃或膦）与 B(2)cat(3) 的反应干净地产生两性离子配合物 [L2Rh(eta(6)-catBcat)] 和 [(acac)Bcat]； [(dppm)Rh(eta(6)-catBcat)]（其X射线结构已报道）是乙烯基芳烃和无张力内烯烃顺式和反式二苯乙烯和反式-β-甲基苯乙烯二硼化的优异催化剂。
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.
