oxides were employed as preligands for the synthesis of catalytically active transition metal complexes of the phosphinous acids (CF3)2POH and (C2F5)2POH. Their reactions with solid PtCl2 and PdCl2 led to the formation of mononuclear phosphinous acid complexes [Cl2MP(Rf)2OH}2] (M = Pd, Pt; Rf = C2F5, CF3), which can be crystallized, for example, as its pyridinium salts, 2[HPy]+[Cl2PdP(CF3)2O}2]2–.
