Abstract
The treatment of 3-chlorobenzo[b]thiophene-2-carbonyl chloride with diethyl- or dipropylcadmium leads to the corresponding ketones, and the treatment of the acid itself with butyl- or propyllithium leads to ketones in admixture with the tertiary alcohol. The subsequent reduction of the ketones obtained with hydrazine hydrate and hydriodic acid has given 2-alkylbenzo[b]thiophenes.
