Practical Reagents and Methods for Nucleophilic and Electrophilic Phosphorothiolations

New late-stage phosphorothiolation methods are disclosed that allow the efficient transfer of SP(O)(OR)2 groups to diversely functionalized substrates using nucleophilic and electrophilic reagents. The nucleophilic reagent, tetramethylammonium O,O-dimethyl phosphorothioate, was synthesized in near-quantitative yield from Me3SiP(O)(OMe)2, elemental sulfur and Me4NF. Its umpolung with N-bromophthalimide provided the electrophilic reagent, O,O-dimethyl-S-(N-phthalimido)phosphorothioate. Complementary methods based on these reagents enable the phosphorothiolation of diversely functionalized alkyl halides, arenediazonium salts, arylboronic acids and electron-rich arenes in good yields under mild conditions.

Reactions of Aromatic Diazonium Salts with Esters of Acrylic and Methacrylic Acids in the Presence of O,O′-Diethyl Phosphodithioates

Alkyl 2-(diethoxythiophosphorylthio)-2-phenylpropionates were prepared by reaction of aromatic diazonium salts with esters of acrylic and methacrylic acids in the presence of potassium O,O′-diethyl dithiophosphate in a water-acetone (1 : 2) medium. The reaction is accompanied by formation of aryl O,O′-diethyl phosphodithioates. The diethoxythiophosphorylthioarylation of acrylates readily occurs in the absence of copper salts, thus providing an example of a noncatalytic reaction of diazonium salts with unsaturated compounds in the presence of foreign nucleophiles.

Method for preparation of phosphorus polysulfides

A process for the preparation of phosphorus polysulfides which comprises reacting a compound containing one or more --SH radicals with a sulfenamide characterized by the presence of a carbonyl group adjacent to the sulfenamide nitrogen wherein one or both of the SH compound and sulfenamide contains a phosphoryl moiety.
