1.3- Benzodithiole-2-carbene

Alkoxy-l, 3-benzodithioles (1). Carbon disulfide undergoes 1,3-dipolar cycloaddition to benzyne [generated from benzenediazonium-2-carboxylate (1,46)] to give 1,3-benzodithiole-2-carbene (a). This carbene reacts with alcohols to form (1) in 35-50% yields. The reaction can be carried out in one-step from anthranHic acid, since carbon disulfide is more reactive than alcohols toward benzyne. ... [Pg.96]
