The reaction of 1,3-dibutyl-2-ethoxy-4,5-dimethyl-2-oxo-1,3,2-diazaphosphol-4-ene with tetracyanoethylene

The reaction of 1,3-dibutyl-2-ethoxy-4,5-dimethyl-2-oxo-1,3,2-diazaphosphol-4-ene with tetracyanoethylene gives 6-amino-1,3-dibutyl-5-cyano-2-ethoxy-4-(1-imino-2-cyanoethyl)-2-oxo-1,3,2-diazaphosphindane.Translated fromIzvestiya Akademii Nauk.

Electrooxidation of 2,3-dihydro-1H-1,3,2-diazaphospholes

Electrooxidation of 2-R-1,3-dibutyl-4,5-dimethyl-2,3-dihydro-1H-1,3,2-diazaphospholes with tri- and tetracoordinated phosphorus atoms were studied. Reversible one-electron oxidation gives radical cations at potentials of −0.37 to +0.36 V. Magnetic parameters of the radical cations were measured. Translated fromIzvestiya Akademii Nauk.

Quantumchemical Investigation of Unsaturated Sixmembered Heterocycles: I. Steric and Electronic Structures of 1,2-dihydro-1,2-azaphosphorin

By quantumchemical calculations of 1,2-dihydro-1,2-azaphosphorin by semiempirical and abinitio calculations we discovered that in gas phase it has twist form with planar nitrogen and pyramidal phosphorus atoms, the latter with a pseudoaxial substituent. The N-H and P-H bonds occupy anticlinal positions.     

Reaction of trialkyl phosphites with 1,1,1-trifluoroacetone

Conclusions Trialkyl phosphites react with 1,1,1-trifluoroacetone to give 2,2,2-trialkoxy-3,5-dimethyl-3,5-bis(trifluoromethyl)-1,4,2-dioxaphospholanes, which slowly isomerize to trialkoxy--trifluoromethyl--(1-methyl-2,2-difluorovinyloxy)ethoxyfluorophosphoranes.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 4, pp. 910–914, April, 1980.     

Synthesis of ethyl bis(N-butyl-N-isobutenylamido)phosphite and reaction with α-chloroacetaldehydes

Conclusions Some vinyl bis(N-butyl-N-isobutenylamido)phosphates were synthesized, which exhibited herbicidal activity.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 3, pp. 700–702, March, 1982.
