Abstract
Naphtho [1, 8-de][1, 3] dithiin-1-bis (ethoxycarbonyl) mcthylides (3) were prepared by the reaction of naphtho [1, 8-de] dithiins with dicthyl diazomalonate in the presence of copper acetylacetonate. The sulfonium ylides 3 underwent photo-rearrangement giving olefins 5 quantitatively together with naphthalene-1, 8-dithiole.
