Reaction of 2-phenylamino-1,3,2-dioxaphospholane with phenyl isocyanate

Conclusions The reaction of 2-N-phenylamino-1,3,2-dioxaphospholane with phenyl isocyanate proceeds to give N,N-bis(1,3,2-dioxaphospholanyl)phenylamine and diphenylurea due to the reversible disproportionation of the starting amidophosphite to N,N-bis(1,3,2-dioxaphospholanyl)phenyl-amine and aniline.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 1, pp. 216–218, January, 1978.     

Molecular structure of (diethyldithiocarbomoyl)diphenylthiophosphinate

X-Ray study of (diethyldithiocarbomoyl)diphenylthiophosphinate was carried out. AZ-conformation of the diethyldithiocarbomoyl ligand, which results in a short nonvalent intramolecular P...S contact (3.315 Å), is realized in the molecule. Steric hindrances in the molecule increase the P-S-C bond angle to 106.39°.Translated fromIzvestiya Akademii Nauk. Seriya Khimicheskaya, No. 10, pp. 1978–1980, October, 1995.The work was financially supported by the International Science Foundation (Gram RH1 000).     

Reaction of teimethylsilyl bis(diethylamido) phosphite with proton-containing reagents

Conclusions Depending on the nature of the proton donor, trimethylsilyl bis(diethylamido)phosphite reacts with proton-containing reagents like HCl, alcohol, and aniline in a variable manner. Trimethylsilyl diethyl-amidochlorophosphite and the amine are formed in the reaction with HCl. Tetraethyldiamidophosphite and either trimethoxysilane or diethylaminosilane are formed when reaction is with either alcohol or aniline.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 2, pp. 463–466, February, 1976.     

REACTIONS OF TETRAPHOSPHORUS DECASULFIDE AND LAWESSON'S REAGENT WITH SILANES CONTAINING A FEW Si-O BONDS

Abstract

The reactions of tetraphosphorus decasulfide and Lawesson's reagent with tetra-, tri- and dialkoxysilanes were studied. On the basis of these reactions, new S-silyl esters of phosphorus(V) thioacids have been prepared. The prepared compounds were identified by IR, ¹H, and ³¹P NMR and mass spectra as well as elemental analyses.     

Influence of Iodine on Reactivity of Phosphorus Sulfides and Homologues of Davy's Reagent in Organic Reactions

Abstract

The use of iodine results in reactivity enhancement of phosphorus sulfides and homologues of Davy's reagent in the reactions with disulfides, aminals and thioacetals. The reactions β-diiodotetraphosphorus trisulfides with disulfides, aminals and thioacetals were studied.     

TETRAPHOSPHORUS TRISULFIDE IN REACTIONS WITH THIOACETALS,AMINALS, SULFENAMIDES AND DISULFIDES. INFLUENCE OF AMINES AND BENZOYL PEROXIDE

Abstract

The reactions of tetraphosphorus trisulfide with thioacetals, aminals, sulfenamides and disulfides were studied. The reactions were found to give organothiophosphorus compounds and to be facilitated by organic amines and benzoyl peroxide.     

Organic Phosphorus-Suflur Compounds Derived from 1,3,2λ5,4λ5-Dithiaphosphetane 2,4-Disulfides. Synthesis and Properties

The results of author's research into the thiophosphorylating ability of 1,3,2⁵,4⁵-dithiadiphosphetane 2,4-disulfides in reactions with Group II, IV, V, and VI p-element derivatives containing E-X bonds (X = O, S, N) are summarized. New syntheses of organic phosphorus-sulfur compounds with P(S)SE (E = B, Al, C, Si, Ge, Sn, Ph, P, As, Sb, Bi, S) structural fragments are developed. Structural peculiarities and spectral and chemical properties of a series of representatives of these classes of organophosphorus compounds are discussed.
