摘要：

Reaction of 1,3-dimetallated acetylenes KC = C-CH(K)R (R = alkyl, O-alkyl, S-alkyl, aryl, N(alkyl)2) with non-enolizable thiocarbonyl compounds XCSSCH3 (X = aryl, heteroaryl, t-Bu, CH3O, t-BuO, CH3S, N(alkyl)2) gives 2,3-disubstituted thiophenes (6) having X in the 2-position and R in the 3-position.
