Abstract

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, [R2PhP(CH2)nPPh3]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.
