2,3-Dihydro-2,3-bis-(methylene)thiophene and its benzo derivative, generated flash-pyrolytically, polymerise or are trapped with HCl and PhSH but only the latter gives Diels-Alder adducts; electrocyclisation of the 3-phenylmethylene derivative is accompanied by skeletal rearrangement to give naphtho[1,2-b]thiophene.
快速热解生成的2,3-二氢-2,3-双-(亚甲基)噻吩及其苯并衍生物聚合或被HCl和PhSH捕获,但只有后者能产生Diels-Alder加合物。3-苯基亚甲基衍生物的电环化伴有骨架重排,得到萘并[1,2-b]噻吩。
