Deskripsi
Reaction of heterometallic cubane-type cluster complexes—[Mo<sub>3</sub>{Pd(dba)}S<sub>4</sub>Cl<sub>3</sub>(dbbpy)<sub>3</sub>]PF<sub>6</sub>, [Mo<sub>3</sub>{Pd(tu)}S<sub>4</sub>Cl<sub>3</sub>(dbbpy)<sub>3</sub>]Cl and [Mo<sub>3</sub>{Pd(dba)}S<sub>4</sub>(acac)<sub>3</sub>(py)<sub>3</sub>]PF<sub>6</sub>, where dba—dibenzylideneacetone, dbbpy—4,4′-di-<i>tert</i>-butyl-2,2′-bipyridine, tu—thiourea, acac—acetylacetonate, py—pyridine, with white phosphorus (P<sub>4</sub>) in the presence of water leads to the formation of phosphorous acid H<sub>3</sub>PO<sub>3</sub> as the major product. The crucial role of the Pd atom in the cluster core {Mo<sub>3</sub>PdS<sub>4</sub>} has been established in the hydrolytic activation of P<sub>4</sub> molecule. The main intermediate of the process, the cluster complex [Mo<sub>3</sub>{PdP(OH)<sub>3</sub>}S<sub>4</sub>Cl<sub>3</sub>(dbbpy)<sub>3</sub>]<sup>+</sup> with coordinated P(OH)<sub>3</sub> molecule and phosphine PH<sub>3</sub>, have been detected by <sup>31</sup>P NMR spectroscopy in the reaction mixture.
