摘要

Abstract 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.
