using nucleophilic and electrophilicreagents. 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 electrophilicreagent, O,O‐dimethyl‐S‐(N‐phthalimido)phosphorothioate. Complementary methods based on these reagents enable the phosphorothiolation
Organometallicreagents attack the SS bonds of phosphorothionyl disulphides (V) to give high yields of the corresponding S-substituted phosphorodithioates. S-alkenyl and S-alkynyl phosphorodithioates, previously unknown, were prepared in this manner. No indication of attack at phosphorus atoms, of reduction of SS bonds, or of benzylic rearrangements of the organo- metallic reagents were observed

As is known, O,O'-diethyldithiophosphoric acid derivatives are used as physiologicallyactivecompounds with a broad spectrum of biological activity [ l, 2]. It would be also of interest to study in this respect a series of previously undescribed l-(O,O'-diethyldithiophosphato)l-alkoxycarbonyl2-phenylethanes. This work continues our earlier investigations [3 5] and is aimed at the development of a

An environmentally friendly and resourceful modular protocol for the synthesis of phosphorochalcogenoates, phosphorochalcogenothioates, and phosphinothioates under blue light-emitting diode irradiation is described. The blue LED-promoted P–S, P–Se, and P–Te bond constructions occurred under metal-free, ligand-free, oxidant-free, and photocatalyst-free conditions with minimum chemical waste generation

method allows for the preparation under simple conditions of a broad range of S-aryl phosphorothioates, including complex molecules (e.g., dinucleotide or TADDOL derivatives), as well as other related organophosphorus compounds arylated at a chalcogen. The reaction proceeds with a full retention of the stereogenic center at the phosphorusatom, opening convenient access to P-chiral products. The mechanism
