Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): 1,2,4-TRIAZHIES -- HETERYLPORPHYRINS -- MESO-TETRAARYLPORPHYRINS -- NONSYMMETRICAL PORPHYRINS -- QUINAZOLINE Аннотация: In the reaction with quinazoline and 5-phenyl-1,2,4-triazin-5(2H)-one, 5,10,15,20-tetra(4-methoxyphenyl)porphyrin exhibits nucleophilic properties. In quinazoline excess, C-C coupling occurs at the C=N bond of azines and position 3 of the aryl ring to form 5,10,15,20-tetrakis(3-heteryl-4-methoxyphenyl) porphyrins. Monoheteryl-substituted porphyrin was obtained by the reaction of equimolar amounts of 5,10,15,20-tetra(4-methoxyphenyl)porphyrin and 5-phenyl-1,2,4-triazin-5(2H)-one. \\\\Expert2\\nbo\\Russian Chemical Bulletin\\2004, 53 (1), 160.pdf |
