Abstract
Naphtho[1,8-de] [1,3]dithiin-1-bis(cthoxycarbonyl)methylides (3) were prepared by the reaction of naphtho[1,8-de]dithiins with diethyl diazo malonate in the presence of copper acetylacetonate. The sulfonium ylid es 3 underwent photo-rearrangement giving olefins 5 quantitatively tog ether with naphthalene-1,8-dithiole.
