Diphenylacetylenes are obtained when alkyllithium reagents are added to 3-aryl-2-fluorobenzothiophenes at low temperature. The aromatic ring-opening mechanism involves a nucleophilic addition of the alkyllithium to the sulfur atom of the thiophene. The re
3-ARYL-3H-1,2-BENZODITHIOLES. SYNTHESIS AND REACTION WITH DICHLOROCARBENE AND CARBENOID

New stable 3H-1,2-benzodithiole derivatives, 3-aryl-3H-1,2-benzodithioles, were synthesized.While the reaction of the 3-aryl-3H-1,2-benzodithioles with CH2I2-Et2Zn gave methylene-inserted products 4-aryl-2,4-dihydro-1,3-benzodithiins, the reaction with dichlorocarbene afforded unexpected products 2-chloro-3-arylbenzothiophenes
