Derivatives of a new heterocyclic quinoid system, viz., 3,4,7,8-bis (3-R-benzo)-2,6-dithia-1,5-diaza-2,6-dihydroanthracene 2,6-dioxide, were synthesized by the oxidation of 3,4,7, 8-bis (3-R-benzo)-2,6-dithia-1,5-diaza-1,2,5,6-tetrahydroanthracene 2, 6-dioxides with lead tetraacetate in acetic acid or with phenyliodoso diacetate in benzene.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 3, pp. 343–345, March, 1985. 相似文献

The synthesis of 2,6-bis-hydrazonopyridines from 2,6-bis-hydrazinopyridine and the conversion of these bis-hydrazones into 2,6-bis-indazol-1-ylpyridines were studied. The conversion of bis-haloarylhydrazones to bis-indazoles was systematically optimized using iron and copper mediated reactions and various bases and ligands. By varying solvent, base, transition metal, and ligand, a novel regiospecific route to the 2,6-bis-indazol-1-ylpyridine class of ligands was developed. 相似文献

High molecular weight, film-forming, amorphous polyesters have been prepared from 2,6-dilydroxy-9,10-dihydro-9,10-ethanoanthracene with adipic, sebacic, dodecanoic, isophthalic, 4,4′-oxybibenzoic, 2,6-naphthoic, 4,4′-bibenzoic, and terephthalic acid. Thermal elimination of ethylene from these polymers has yielded the corresponding polyesters from 2,6-dihydroxyanthracene which were of high molecular weight, film forming, and crystalline. 相似文献

Conclusions The reactions of organyl ,-dichlorovinyl sulfones with sulfur-containing nucleophiles, viz., sodium sulfide and salts of alkylxanthic acids, have been studied. A preparative method for synthesizing heretofore unknown 2,6-bisorganylsulfonyl-1,4-dithiafulvenes from organyl ,-dichlorovinyl sulfones and Na2S·9H2O in ethanol has been proposed. The isomeric composition of the compounds synthesized was studied, and their easy isomerization in an acidic medium has been established.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 2, pp. 368–372, February, 1980. 相似文献
