Reaction of elemental phosphorus (P4) with thiophenol in the presence of amines

Elemantal phosphorus (P4) reacts with thiophenol and amines at elevated temperature in acetonitrile to give ammonium or acetimidamidium S,S-diphenyl phosphorodithioates, depending on the nature of the amine. Analogous salts were isolated in the

Isotope Effects on 31P Nuclear Shielding in Thiophosphites

The 34S isotope effect on the chemical shift of PIII nuclei in P(SR)3 esters is close to 20.6 ppb per PIII-34S bond, i.e. 3-4 times larger than for thiolo sulphur atoms in S=P(SR)3.A similar behaviour is noted for the P(-S-)3 sites in P4S9 and P4S3 and for the downfield triplet of P4S8, which, accordingly, is assigned to the tri-coordinate P atoms of this sulphide. 13C isotope effects are also reported for trialkyl(aryl) phosphorotrithioites and S,S,S-phosphorotrithioates.

Organophosphorus Antioxidants. X. The Hydroperoxide Decomposing Action of Phosphites, Phosphonites and Thiophosphites

The kinetics and mechanism of reactions of phosphites, phosphonites, thiophosphites and hydrogenphosphites with cumyl (CHP), t-butyl (TBHP) and α-tetralyl (THP) hydrogenperoxides has been studied by means of (31)P-n.m.r. spectroscopy, high performance liquid chromatography and iodometric titration.All three valent phosphorus compounds studied initially react with hydroperoxides stoichiometrically to give the corresponding P=O products and alcohol.Some species are able to decompose cumyl hydroperoxide catalytically to form phenol and aceton.Acyloin phosphites decompose CHP catalytically after a stoichiometric reaction as thiophosphites do.Tetramethylpiperidinyl phosphites ("HALS-phosphites") react with hydroperoxides only stoichiometrically but with high velocity.Phosphonites react with hydroperoxides in the same way as the corresponding phosphites.Their reactivity, however, is much higher.Hydrogenphosphites are less reactive than phosphites in the reaction with hydroperoxides.They are able to act catalytically.

RADICAL DECARBOXYLATIVE PHOSPHORYLATION OF CARBOXYLIC ACIDS

Thiohydroxamic carboxylic mixed anhydrides (e.g. 1) react at room temperature with (PhS)3P to give, through a decarboxylative phosphorylation reaction, the corresponding dithiophosphonates 12 in moderate yields.
