Synthesis of new dialkyl α-aminophosphonates and dialkyl α-aminothiophosphonates

New dialkyl α-aminophosphonates and α-aminothiophosphonates were synthesized by reactions of dialkyl phosphites orO,O-dialkyl thiophosphites withN-benzylidene 2-(vinyloxy)ethylamine orN-(4-fluorobenzylidene)-2-(vinyloxy)ethylamine.

Synthesis and insectoacaricidal activity of S-benzhydryl esters of phosphorus dithio- and monothioacids

Conclusions We synthesized a number of S-benzhydryl esters of phosphorus dithioacids that possess insectoacaricidal properties, in which connection the most active ester, O-ethyl S-benzhydryl methyldithiophosphonate, has the same contact activity as Chlorophos and Rogor.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 9, pp. 2170–2172, September, 1978.     

Nitration of alkenylphosphonates with nitrogen tetraoxide

Conclusions A new method was developed for the synthesis of organophosphorus nitro compounds, which consists in the direct nitration of alkenylphosphonates with N₂O₄.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 12, pp. 2787–2788, December, 1977.     

Intramolecular P=S and P=N Alkylation. General Method for Synthesizing 1,2-Heteraphosphacyclanes

Results have been generalized for investigations on the synthesis of 1,2-thiaphosphacyclanes by intramolecular P=S alkylation of -haloalkyl substituted compounds of four-coordinated phosphorus with a P=S bond. The method has been extended to nitrogen-containing analogs with a P=N bond. A new general method is proposed for the synthesis of 1,2-thia- and 1,2-azaphosphacyclanes.
