Charushin, K. A. Khlamkin, I. A. Utepova // Russian Chemical Bulletin (Translation of Izvestiya Akademii Nauk, Seriya Khimicheskaya). - 2015. - Vol. 6, № 5. - С. 1093-1096 Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): MESO-SUBSTITUTED CALIXARENES -- MESO-SUBSTITUTED AZINYLCALIXARENES -- METAL CATALYSIS Аннотация: Earlier unknown meso-substituted azinylcalixarenes were obtained by a direct cross-coupling of 2-lithium-25,26,27,28-tetramethoxycalix[4]arenes with mono- and diazine N-oxides without transition metal catalysis. \\\\expert2\\nbo\\Russian Chemical Bulletin\\2015, 64 (5), 1093-1096.pdf |
