Abstract

The interaction of Li2M(NBut)4 (M = W, Mo) and PX3 (X = Cl, Br) produces yellow crystalline compounds of stoichiometry M(NBut)X2[P2(NBut)3], M = W, X = Cl (1a), Br (1b), M = Mo, X = Cl (2). The interaction of W(NBut)Cl2[P2(NBut)3] (1a) with TlSC6F5 gives a mono-substituted product (3) but TlOC6F5 produces a disubstituted compound (4). The X-ray crystal structures of 1b and 3 have been determined. In both cases the iminophosphine ligand is tridentate with W-NBut linkages and the geometry is octahedral.
