New 15(18)-crown-5(6)-containing and model methoxy-substituted 1-hetaryl-2-phenylacetylenes of the 4-pyridine and 2-benzothiazole series were synthesized using the addition of bromine to the ethylene fragment of the corresponding styrylheterocycles followed by dehydrobromination under the action of potassium tert-butoxide. The quaternization of the pyridylphenylacetylenes afforded new acetylenyl dyes. The structures of five synthesized compounds were determined by X-ray diffraction analysis.
在叔丁醇钾的作用下,将溴加到相应苯乙烯杂环的乙烯片段上,然后进行脱氢溴化,合成了 4-吡啶和 2-苯并噻唑系列的新的含 15(18)-冠-5(6)和模型甲氧基取代的 1-芳基-2-苯乙炔。将吡啶苯乙炔季铵化后可得到新的乙炔染料。通过 X 射线衍射分析确定了五种合成化合物的结构。
