GENERATION AND REACTIONS OF 2,3-DIHYDRO-2,3-bis-(METHYLENE)THIOPHENES

2,3-Dihydro-2,3-bis-(methylene)thiophene and its benzo derivate, generated flash-pyrolytically, polymerise or are trapped with HCl and PhSH but only the latter gives Diels-Alder adducts; electrocyclisation of the 3-phenylmethylene derivate is accompained by skeletal rearrangement to give naphthothiophene.
