Abstract
Abstract The cyclization of (2-bromophenyl)thioacetic acid morpholide to 2-(morpholin-4-yl)-1-benzothiophene in the presence of copper(II) chloride has been found to involve intermediate formation of a complex consisting of two thioamide molecules and one copper cation. The complex has been isolated, and its molecular structure parameters have been determined by quantum chemical calculations.
