Methylenverbindungen von Nichtmetallen, III [1]. Metallcarbonyl-Komplexe mit methylenverbrückten Diphosphor-Liganden / Methylene Compounds of Non-Metals, III [1] Metal Carbonyl Complexes of Methylene-Bridged Diphosphorus Ligands

Abstract

Compounds of the type R2PCH2PR2 (R = PriO, Me2N) react with cis-LM(CO)4 (L = Bicyclo[2,2,1]hepta-2,5-dien; M = Cr, Mo, W) complexes to yield cis-substituted [R2PCH2PR2]M(CO)4 derivatives. The structure of the molybdenum compound, [(PriO)2PCH2P(OPri)2]Mo(CO)4, has been determined. Diphosphorus ligands of the type R2P(S)CH2PR2 (R = F, PriO) are monodentate and form [R2P(S)CH2PR2]2Mo(CO)4 complexes, whereas the compound (Me2N)2P(S)CH2P(NMe2)2 acts as a bidentate ligand
