Reaction of Na/sub 2/Cr(CO)/sub 2/ with a bulky monosubstituted phosphorus(III) halide, RPCl/sub 2/, where R = 2,4,6-Me/sub 3/C/sub 6/H/sub 2/ (Mes), CH/sub 2/SiMe/sub 3/, CH(SiME/sub 3/)/sub 2/, N(SiMe/sub 3/)/sub 2/, or -OC/sub 6/H/sub 2/-2,6-t-Bu/sub 2/-4-Me, leads to at least nine different types of product which may involve diphosphene, phosphinidene, phosphane, diphosphane, and cyclopolyphosphane ligands. The products obtained depend markedly on the size and electronic properties of the substituent on phosphorus. The synthesis and properties of 12 compounds of which 10 have been structurally characterized by x-ray crystallography are described in this paper.
