Catalyst- and oxidant-free coupling of disulfides with H-phosphine oxide: construction of P–S bond leading to thiophosphinates

An efficient protocol for the synthesis of thiophosphinates is presented, involving direct coupling of P–S bond between disulfides and H-phosphine oxide in moderate to good yields with good functional group compatibility. This procedure shows some advanta

Benign synthesis of thiophosphates, thiophosphinates and selenophosphates in neat condition using N-chalcogenoimides as the source of electrophilic sulfur/selenium

A neat reaction protocol has been developed for synthesis of thiophosphate, thiophosphinate and selenophosphate compounds. N-chalcogenoimides have been used for chalcogenylation of P(O)H moieties of various H-phosphonates under solvent, catalyst and base free condition at room temperature in aerial atmosphere. Both S-aryl and S-alkyl phosphorothioate compounds were prepared by this method in good yields. Selenophosphates were also synthesized using N-(phenylseleno)phthalimide under solvent free condition.

Cs2CO3-Catalyzed Aerobic Oxidative Cross-Dehydrogenative Coupling of Thiols with Phosphonates and Arenes

An efficient Cs2CO3-catalyzed oxidative coupling of thiols with phosphonates and arenes that uses molecular oxygen as the oxidant is described. These reactions provide not only a novel alkali metal salt catalyzed aerobic oxidation, but also an efficient approach to thiophosphates and sulfenylarenes, which are ubiquitously found in pharmaceuticals and pesticides. The reaction proceeds under simple and mild reaction conditions, tolerates a wide range of functional groups, and is applicable to the late-stage synthesis and modification of bioactive molecules.

TBPB-promoted metal-free synthesis of thiophosphinate/phosphonothioate by direct P-S bond coupling

An efficient method for the direct coupling of thiol/thiophenol with H-phosphine oxides or H-phosphinate esters is reported. Without using any metallic catalyst, the direct sulfur-phosphorus bond coupling reaction was promoted using tert-butyl peroxybenzo

Chloroform-based Atherton-Todd-type reactions of alcohols and thiols with secondary phosphine oxides generating phosphinothioates and phosphinates

Chloroform-based Atherton-Todd-type reactions of alcohols and thiols with secondary phosphine oxides, generating phosphinothioates and phosphinates, respectively, are described. Various valuable phosphinothioates and phosphinates including those with functional groups are readily prepared under mild reaction conditions.

Intramolecular homolytic substitution at the sulfur atom: an alternative way to generate phosphorus- and sulfur-centered radicals

Two efficient procedures involving tin hydride or thiophenol-mediated intramolecular homolytic substitution at the sulfur atom are reported. They lead to the generation of varied P(V)-centered radicals from the corresponding aryl or alkyne thiophosphorus substrates. The radical formed can be trapped by an olefin via an intermolecular addition, leading to the construction of C-P bonds. Thiophosphination of triple bonds was also achieved using a radical cycloisomerization process. Extension of the methodology to sulfur-containing species was examined.

Rhodium-catalyzed thiophosphinylation and phosphinylation reactions of disulfides and diselenides

Alkyl and aryl dithiophosphinates were synthesized by the reaction of disulfides with biphosphine disulfides in the presence of RhH(PPh 3)4 and 1,2-diphenylphosphinoethane (dppe). The catalyst also promoted synthesis of thiophosphinates and selenothiophosphinates from disulfides and diselenides.
