V. Berezin, P. A. Slepukhin, G. L. Rusinov, V. N. Charushin // Russian Chemical Bulletin (Translation of Izvestiya Akademii Nauk, Seriya Khimicheskaya). - 2009. - Vol. 58, № 1. - P176-181 Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: The previously unknown addition products of P-nucleophiles to 5-aryl- and 5-hetaryl- 2,3-dicyano-1-ethylpyrazinium salts and to 5-aryl- and 5-hetaryl-14nethylquinoxalinium salts were synthesized. The three-dimensional structures of the P- sigma(H)-adducts of the 1,4-diazine series were established by X-ray diffraction \\\\Expert2\\nbo\\Russian Chemical Bulletin\\2009, 58 (1), 176-181.pdf |
