Notes Unsymmetrical Bis(phosphorus) Compounds: Synthesis of Unsymmetrical Ditertiary Phosphines, Phosphine Oxides, and Diquaternary Phosphonium Salts

A convenient preparative route to the unsymmetrical bidentate phosphines R2P(CH2)nPPh2 (R=Me or Et; n=3 or 4) is described.This involves the synthesis of unsymmetrical diphosphonium salts, Br2, and diphosphine oxides, R2P(O)(CH2)nPPh2, as intermediates.The symmetrical ligand Et2P(CH2)3PEt2 was also prepared by the same route.New co-ordination complexes of manganese(II) with these ligands have been isolated.
