Аннотация:Using the condensation of acetophenone under the action of triethyl orthoformate as an example, the effect of ratios of solvents (CH(OEt)3 and toluene) and the starting reagents on the composition and yields of aromatic products was studied. After treatment of reaction mixtures with ammonia, 1,3,5-triphenylbenzene, m-terphenyl, and 2,6-diphenylpyridine were isolated.
