Treatment of t)2> or with Ph2P(CH2)nP(=O)Ph2 (n=1, dppmO; n=2, dppeO; n=3, dpppO; n=4, dppbO) gives complexes of the type cis-2>, independently of mole ratio.Treatment of cis- with LiBr or NaI gives (X=Br, cis; X=I, cis/trans mixture) and on treatment with Hg(CCPh)2 in ethanol, trans-CPh)2(dppmO)2> is formed.Treatment of these ligands with gives exclusively cis-2>.Coordination of the P=O group was achieved by treating 2> with either AgNO3 or TlPF6, whereupon cis-2>(2+) (n=1, or 2) is formed: these cations were also synthesized by treating O)Ph2>2> with HBF4.Treatment of with dppmO gives trans- only and this reacts with AgNO3 or TlPF6 to form cis-(2+).The complexes were characterized by microanalysis, IR and NMR spectroscopy.
