The pentacoordinate phosphorus molecule, cyclenphosphorane (cyclenPH), is found to be a useful and unique ligand in transition-metal chemistry.It reacts with metal-carbonyl dimers to cleave the dimers and yield covalent phosphoranide-metal complexes and metal carbonyl anions.With cis-Cl2Pt(PPh3)2, two phosphoranide-metal complexes are formed, one ionic and the other covalent.A unique reaction occurs with ClRh(PPh3)3 where, initially, a product is obtained in which one of the P-N bonds of the cyclenP moiety is cleaved.This species undergoes a threefragment oxidative addition of CH2Cl2 to reform the pentacoordinate phosphorus and also form a novel P-N-C-Rh metallocycle.

Cyclenphosphorane reacts with CIRh(PPh3)3 to initially yield a four-coordinate complex where two PPh3 groups have been displaced by the phosphorus and one nitrogen atom of the open form of cyclenphosphorane. This species undergoes a three-fragment oxidative addition of dichloromethane to yield a compound with a phosphoranide-metal bond and a novel P-N-C-Rh metallacycle.
