Smirnov, A. Afanas'ev, L. Belen'kii] The reactions of thiophene, 2-methyl-, and 2-bromothiophene with succinyl dichloride in the presence of AlCl3, TiCl4, and SnCl4 have been studied. The effect of the acylation conditions, the relative amounts and nature of the Lewis acid on the ratio and yields of the 1,4-di(2-thienyl)-1,4-diones and 4-oxo-4-(2-thienyl)butyric acids formed have been demonstrated. Under the reaction conditions, the formation of 4,4-di(2-thienyl)but-3-enoic acids (the main products in many cases) and also 4,4-di(2-thienyl)-butyrolactones was demonstrated.
