Reaction of gem-nitronitroso-compounds with triethyl phosphite

2-Nitro-2-nitrosopropane reacts with triethyl phosphite by deoxygenation of the nitroso- group to give 2-nitriminopropane; 1-nitro-1-nitrosocyclohexane reacts similarly. The reaction proceedsvia an intermediate detectable byNMR; possible structures for this intermediate and for the course of the reaction are discussed. Some reactions of nitrimines are also reported.     

The synthesis of pseudorutaecarpine with triethyl phosphite

Pseudorutaecarpine was synthesized by nitrene reaction of 3-(2-nitrobenzal)-1,2,3,9-tetra-liydropyrrolo[2,1-b]quinazolin-9-one (IV).     

The reaction of trifluoroacetylcyclopentadienylmanganesetricarbonyl with triethyl phosphite

Conclusions Trifluoroacetylcyclopentadienylmanganesetricarbonyl reacts in the cold with triethyl phosphite to form a cyclic pentaoxyphosphorane which has unusual hydrolytic stability.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 1, pp. 159–160, January, 1970.     

Reaction of tartaric acids with triethyl phosphite

Conclusions The formation of the isomeric 2-ethoxy-4,5-di(carbethoxy)-1,3,2-dioxaphospholanes occurs when triethyl phosphite is transesterified with the D-, DL-, and mesotartaric acids.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 3, pp. 653–655, March, 1973.     

Interaction of Mannich bases with triethyl phosphite

Conclusions A study of the kinetics of the reaction of aliphatic ketone Mannich bases with acetic acid indicated that this reaction is a reaction of elimination of vinyl ketone from a salt of the base with the acid and is a first-order reaction.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 4, pp. 825–828, April, 1969.     

Reaction of triethyl phosphite withβ-substituted nitriles

Conclusions Propionitriles having hydroxy, acetate, and phenoxy groups in the-position are capable of undergoing the Arbuzov rearrangement with triethyl phosphite to form diethyl-cyanoethylphosphonate.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 9, pp. 2089–2090, September, 1967.     

A complex of zero-valent cobalt with triethyl phosphite

Conclusions A complex of zero-valent cobalt with triethyl phosphite has been obtained for the first time.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 11, pp. 2041–2042, November, 1966.
