Abstract Generation of phosphide anions from phosphorus red or phosphine under the action of strong bases followed by their reactions with organyl halides, electrophilic alkenes and alkynes proves to be the most straightforward and well-controlled route to mono-, di- or triorganylphosphines or phosphine oxides of diverse structure.
The generation of phosphine PH3 by alkalinehydrolysis of red phosphorus is realized. The subsequent alkylation of PH3 by terminal alkenes and alkynes in basic media leading to the corresponding aliphatic and vinylic phosphine derivatives can occur by two-steps or one-pot reaction by a Michael-like reaction mechanism.

pronounced antibacterial activity [1]. This work was devoted to the search for new efficient antibacterial agents in this series of organophosphoruscompounds. For this purpose we have developed a method for the synthesis of tris2-[4-(l-benzylpyridinio)]ethyl}phosphinoxide trichloride (1I) (previously unreported) and studied its antibacteriai activity. The initial organophosphoruscompounds was represented
Phosphine chalcogenides and their derivatives from red phosphorus and functionalized pyridines, imidazoles, pyrazoles and their antimicrobial and cytostatic activity
Tertiary phosphine oxides, phosphine sulfides, and phosphine selenides containing pyridine, imidazole, and pyrazole groups have been synthesized via the reaction of elemental phosphorus or secondary phosphine oxides with functional pyridines, imidazoles, and pyrazoles. Alkyl tris(2-pyridylethyl)phosphonium iodide and bromide are also obtained by quaternization of the corresponding phosphine. Antimicrobial
