摘要：

Cuboidal cluster aqua complex [Mo3(PdCl)S4(H2O)9]3+ in 4M HCl causes isomerization of (HO)2P(O)(H), (HO)P(O)(H)2, PhP(O)(OH)(H), and Ph2P(O)(H) into hydroxo tautomers P(OH)3, HP(OH)2, PhP(OH)2, and Ph2P(OH) which are stabilized by P coordination to the Pd atom in the cluster. The reactions were followed by 31P NMR and UV/Vis spectroscopy. Hypophosphorous acid H2P(O)(OH) in the presence of the cluster is rapidly oxidized into phosphorous acid; the reaction can be made catalytic. Coordination of PPh3 also takes place, giving [Mo3(Pd(PPh3))S4(H2O)5Cl4]⋅0.5CH3OH⋅3H2O, whose crystal structure was determined.
