Abstract

The halogen dance reaction was utilized for preparation of iodothiophenes. Starting from a set of dihalo-substituted thiophenes, their derivatives, namely, aldehydes, acids, and 2,5-diiodothiophenes, were obtained. Formyl derivatives of thiophenes served as the basis for the synthesis of a number of previously unknown (difluoromethyl)- and (chloromethyl)thiophenes. Convenient and simple synthetic procedures were developed for a set of functionalized thiophenes.
