The first water-soluble tetraphosphorus ruthenium complex. Synthesis, characterization and kinetic study of its hydrolysis

The chemistry of Group 8 metal complexes with phosphinous acids and related P OH ligands

“…The coordination of phosphinous and phosphorous acids to the (η 6 -p-cymene)osmium(II) fragment [OsCl2(η 6 -p-cymene)] was described by Cadierno and co-workers [90]. In particular, they were able to synthesize in moderate to high yields complexes Following analogous studies with iron and ruthenium [15,[38][39][40][41] In the new compounds 137-138, the phosphorus atoms become also stereogenic centers. Nonetheless, according to the spectroscopic data obtained, the formation of both compounds proceeded in a stereospecific manner, the P atoms adopting the same configuration that the osmium atoms present.…”

Hydrolysis of Element (White) Phosphorus under the Action of Heterometallic Cubane-Type Cluster {Mo3PdS4}

“…Moreover, it has been established that the mechanism of this process may involve the formation of binuclear intermediate, when η 2 -P 4 unite is doubly coordinated to two {CpRu(PPh 3 ) 2 } moieties, which is hydrolyzed with the formation of H 3 PO 3 and previously unknown 1-hydroxytriphosphane (PH(OH)PHPH 2 ) as the intermediate of the overall process [6]. Later this process was improved and the kinetic of P 4 hydrolysis was investigated using ruthenium complexes with water-soluble phosphine ligands [7]. There is also a notable example of stabilization of phosphorous acid H 3 PO 3 in its tautomeric form P(OH) 3 on the Ru site [8].…”
