F 94 From 1,2,4-triazines towards Substituted pyridines and their cyclometalled Pt complexes [Electronic resource] / V. N. Kozhevnikov, M. M. Ustinova, P. A. Slepukhin, D. N. Kozhevnikov, Amedeo Santoro, W. Dunkan // Tetrahedron Letters. - 2008. - Vol. 49, № 26. - P4096-4098 : рис. - Библиогр. : с. 4098 (28 назв.) . - ISSN 0040-4039 Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: A new, efficient methodology for the synthesis of substituted thienylpyridines includes the synthesis of 3-thienyl-1,2,4-triazines using simple heterocyclisation followed by easy transformation of the triazine ring to a pyridine through an aza Diels–Alder approach. A variety of substituted pyridines can be easily achieved using cheap, commercially available reagents such as bromoacetylarenes, aroyl hydrazides, norbornadiene, and enamines in various combinations. New thienylpyridines form phosphorescent cyclometallated Pt complexes.?? \\\\Expert2\\nbo\\Tetrahedron Letters\\2008, v. 49, p.4096.pdf |

Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): 1,2,4 TRIAZINES -- TRIAZOL -- INDOLES Аннотация: The reaction between 5-R-6-R1-3-(2-pyridyl)-1,2,4-triazines and benzyne generated in situ in toluene under reflux results in the formation of 10-(1H-1,2,3-triazol-1-yl)pyrido[1,2-a]indoles 3 in up to 60% yields instead of the expected 3-R-4-R1-1-(2-pyridyl)isoquinolines 2. The crystal structure of product 3c and the proposed mechanism for the formation of 3 are reported \\\\expert2\\nbo\\Tetrahedron Letters\\2013, v. 54, p. 6427.pdf |
