在钾/18-冠-6超分子络合物催化下的四氢呋喃溶液中，1，2-二苯乙烷与溴化苄的偶联反应在室温下进行。基于该模型反应，提出了一种以α，α‘-二溴对二甲苯为原料低温合成聚对二甲苯的新方法。固体~(13)C核磁共振和红外光谱为聚合物的结构提供了实验证据。
Coupling of benzyl bromide giving 1,2-diphenylethane was demonstrated to proceed at room temperature in THF solution mediated by the potassium/18-crown-6 supramolecular complex. Based on this model reaction a novel method for the low temperature synthesis of poly(p-xylylene) from α,α′-dibromo-p-xylene is proposed. Experimental evidence of the polymer structure was provided by solid-state 13C NMR and IR spectroscopy.
