Preparation of trans-cbMCl2>-type complexes (P^cb=o-HCB10H10CCH2PPh2 M=Pd, Pt), which readily undergo intramolecular metallation through the B-H bonds of the carborane cage to form exocyclic compounds involving a bond system, is described.Both monomeric compounds, trans-cb>, and bridged complexes, such as , are formed, where (B-P) is intramolecular-metallated carborane phosphine.The bridging bond is readily cleaved under the action of various ligands (pyridine, PEt3, etc.) to form monomeric compounds.
