(Chloromethyl)isocyanatophosphonates(-phosphinates) take up phenol to form carbamates whose -cleavage gives rise to phenyl (chloromethyl)phosphonates(-phosphinates). (Chloromethyl)(thio)phosphinic-(phosphonic) isothiocyanates react with phenol at 20°C in the absence of catalyst to afford phenyl phosphinates(-phosphonates). (Alkylsulfanyl)carbamates formed by addition of thiols to (chloromethyl)iso(thio)cyanastophosphonates(-phosphinates) under the action of an equimolar amount of triethylamine undergo cyclization into 1,3,4-oxaza(thiaza)phospholines.Translated from Zhurnal Obshchei Khimii, Vol. 74, No. 9, 2004, pp. 1441–1446.Original Russian Text Copyright © 2004 by Khailova, Bagautdinova, Shaimardanova, Krepysheva, M. Pudovik, Chmutova, Azancheev, Musin, A. Pudovik.This revised version was published online in April 2005 with a corrected cover date. 相似文献

The stability of phosphorylated ureas and thioureas containing various substituents at the P and N atoms and the stability of their cyclization products, the corresponding diazaphospholidines and/or oxaza(thiaza)phospholines, was evaluated by PM3, MNDO, and DFT calculations. The thermal effects of cyclizations involving phosphorylated ureas (or thioureas) and of separate steps of their synthesis were calculated. According to the calculations, diazaphospholidine structures are preferably formed from substituted ureas and thiazaphospholine structures, from their thio analogs; formation of five-membered heterorings with the P-N bond is thermodynamically preferable as compared to their six-membered analogs. 相似文献

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.

The reaction of dialkylsilylphosphites with linear and cyclic secondary amines leads to the formation of acid alkoxydialkylamidophosphites and dialkyl phosphites. Aminolysis of pyrocatecholsilylphosphite was accomplished with retention of the phosphorus atom and formation of the corresponding amidophosphites.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 1, pp. 235–237, January, 1991. 相似文献

The reactions of S-benzyl diphenylthiophosphinite and 2-benzylthio-4,5-benzo-1,3-dioxaphospholane with methyl iodide have been examined. In contrast to the oxygen analogs, the reaction occurs under mild conditions, and does not give Arbuzov reaction products.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 12, pp. 2856–2857, December, 1991. 相似文献

Some newS-phosphorylated,S-silylated, andS-stannylated derivatives of -mercaptoketones were obtained. The reactions of some of these compounds induced by the temperature and by molecular oxygen as well as the phosphorylation of the Si- and Sn-containing derivatives were studied.Translated fromIzvestiya Akademii Nauk.

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). 相似文献

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. 相似文献
