The acylation of 4-chloro-2-nitroaniline by ,3-unsaturated acids in the presence of a threefold excess of phosphorus pentoxide has been studied. The 4-chloro-2-nitroanilides of acrylic, methacrylic, crotonic, cinnamic, ß,ß-dimethylacrylic, and ,ß,ß-trichloroacrylic acids have been obtained for the first time. 相似文献

Selected imines and one bis-imine react via their enamine tautomers with terminal perfluorinated epoxides, e.g. hexafluoropropene oxide to produce fluorinated enamino ketones or imino ketones. In contrast, internal perfluorinated linear epoxides and one cyclic epoxide yield intermediate imino alcohols, which in one case added hexafluoroacetone, furnishing a new imino diol investigated by X-ray diffraction. 相似文献

A method has been developed for obtaining 3-vinylbenzoxazolinones and 3-vinylbenzoxazolinethione. It has been shown that it is also possible to obtain 3-methylbenzoxazolinethione by this method in good yield (76%).Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR, Tashkent.

1,2,3,4-Tetrahydro-2-quinolone and -6-(1,2,3,4-tetrahydro-2-quinolonyl)butyric acid were obtained by condensation of acetanilide with -butyrolactone in the presence of aluminum chloride. -n-(N-phenylbutyrolactamyl)butyric acid was obtained by carboxyalkylation of N-phenylbutyrolactam with -butyrolactone.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 1, pp. 77–79, January, 1973. 相似文献

An x-ray structural investigation of the synthesized title compounds (1) and (2) has been performed. The heterocycle of 1 has a boat-chair conformation with the P2=O2 bond in the axial position. The heterocycle of 2 has a distorted-boat conformation with the C6=O carbonyl in the plane of one of the fused benzene rings. The P2=O2 bond is in a pseudoequatorial position.A. E.

The complexation behaviour of cis- und trans-3-diphenylphosphino-4-hydroxyl-tetrahydrofurans with [Rh(COD)2]BF4 is studied with the help of NMR and IR spectroscopy. In dependence of the spatial arrangement of hydroxyl and phosphino group the formation of different intra- and intermolecular bridged O-P complexes has been observed.
Zusammenfassung
Das Komplexierungsverhalten von cis- und trans-3-Diphenylphosphino-4-hydroxy-tetrahydrofuranen mit [Rh(COD)2]BF4 wird mit Hilfe von NMR- und IR-Spektroskopie studiert. In Abhängigkeit von der räumlichen Anordnung von Hydroxy- und Phosphinogruppe zueinander wird die Bildung von intra- bzw. intermolekular verbrückten O-P-Komplexen beobachtet. 相似文献

The review is devoted to the study of the alkaloids of plants of the genusUngernia (Amaryllidaceae). It gives their characteristic reactions and information on the determination of their structures and stereochemistry and on the dynamics of the accumulation of alkaloids in the plants of the genusUngernia. A dependence of the physiological activity of the alkaloids on their structure is shown. 相似文献
