The reactions of thiophene, 2-methyl-, and 2-bromothiophene with succinyl dichloride in the presence of AlCl3, TiCl4, and SnCl 4 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.
