Crystal structure of ω-diazoacetophenone

Conclusions There is no direct conjugation of the phenyl ring with the diazocarbonyl fragment in the crystal structure of -diazoacetophenone. The planar molecular structure is a result of the effect of the crystal field on the molecular shape.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 9, pp. 2023–2026, September, 1985.     

Esters fromFerula stylosa

From the total extractive substances of the roots ofFerula stylosa two esters have been isolated: chimganin and a new one — stylosin. The structure of stylosin is suggested as the ester of 4-hydroxy-3-methoxybenzoic acid and the monoterpene alcohol fenchol.     

Nonstandard formulation of perturbation theory for Green's function

Perturbation theory is developed for two-variable Green's functions (GF) when the initial GF is linked simultaneously to several higher-order GF. The total mass operator of the initial GF is obtained mathematically correctly in a form convenient for use. As an example of the application of this method, the mass operator of a nuclear spin anticommutator GF is calculated.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 7, pp. 43–49, July, 1988.     

Pyrroles from ketoximes and acetylene

The respective 2-aryl- and N-vinyl-2-arylpyrroles were obtained by the reaction of the oximes of alkyl aryl ketones with acetylene in the superbasic medium MOH (M=Li, K)-DMSO. Their yields depended largely on the structure of the ketoximes and on the reaction conditions.For Communication 41, see [1].Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 5, pp. 609–613, May, 1992.
