substituted calix[4]arene dithianes has been prepared from respective formyl and acetyl derivatives. Shorter reaction time, mild conditions, and facile isolation of desired products are attractive features of the described method. The new 1,2-dithiane derivatives have been characterized by 1H NMR, 13C NMR spectroscopy, and FABMS analysis. The crystal structure of one of the acetyl calix[4]arene dithiane
由各自的甲酰基和乙酰基衍生物制备了六个新的不同取代的杯[4]亚芳基二噻烷族。较短的反应时间,温和的条件以及所需产物的容易分离是所述方法的吸引人的特征。通过1 H NMR,13 C NMR光谱和FABMS分析对新的1,2-二噻吩衍生物进行了表征。通过X射线衍射分析确定了乙酰杯[4]亚芳基二噻吩之一的晶体结构,揭示了双噻吩封端的线性分子结构。作为过渡金属离子分子受体的双(二噻吩)杯[4]芳烃衍生物的初步评估显示,其与Hg 2+的化学计量比为1:1。
