摘要： Errede等曾利用氢氧化邻甲基苄基三甲基铵的热解制得螺二邻二亚甲基苯、环二邻二亚甲基苯和聚邻二亚甲基苯。Winberg等人对噻吩的季铵碱的热解有所研究,但未能触及活泼的中间体2,3-二亚甲基-2,3-二氢化噻吩Ⅷ及其二聚体螺环化合物和环状化合物。

Abstract: Degradation of 3-methyl-2-thenyltrimethylammonium hydroxide generates 2,3-dimethylene-2, 3-dihydrothiophene which can be dimerizcd to form spiro-di-ο-methy lenethiophene (Ⅰ),cyclo-di-ο-methylenethiophene(Ⅱ) and poly-ο-methylene-thiophene(Ⅲ).
