Synthesis of P(O)-S organophosphorus compounds by dehydrogenative coupling reaction of P(O)H compounds with aryl thiols in the presence of base and air

The synthesis method of P(O)-S organophosphorus compounds by dehydrogenative coupling reaction of P(O)H compounds and aryl thiols was developed. The reaction was carried in the presence of a base and air, and exhibited good characters such as metal-free,

Direct synthesis of thiophosphates by reaction of diphenylphosphine oxide with sulfonyl chlorides

A new method for the synthesis of thiophosphates by reductive coupling reaction of diphenylphosphine oxide and sulfonyl chlorides has been developed. The reaction is metal-free and needs no additives, affording various aryl and alkyl substituted thiophosphates in good to excellent yields under mild conditions.

Oxidative hydrolysis of phosphorus(V) esters of thiols by peroxymonosulfate ion. Reactions of peroxymonosulfate ion with phosphorus(V) esters of thiols

Peroxymonosulfate ion, HSO5-, as Oxone, readily converts phosphorus(V) esters of thiols into the phosphorus(V) and sulfonic acids. The esters were Ph2PO·SC6H4R(p) with R=MeO (1a), Me (1b), H (1c), Cl (1d) and NO2 (1e), (EtO)2PO·SPh (2), Ph2OI·SEt (3) and PhPO(OEt)SEt (4). Reactions are first order in each reactant and second-order rate constants, k2, for 1a-e fit the Hammett equation with ρ=-0.46. The rate constants increase markedly with increasing water content of H2O-MeCN, the activation enthalpies are low and the entropies are negative. Despite the low value of -ρ, these esters are much less reactive than thiol ethers, but the rate constants of reactions of these compounds and acyl thiols qualitatively follow the ionization potentials of the ethers and the esters.
