摘要

Transition metal-catalyzed cross-coupling reactions of polyhalogenated molecules are of considerable current interest. 15 Recently, we have reported the synthesis of aryl-substituted thiophenes, 16 pyrroles, 17 and selenophenes 18 based on regioselective Suzuki–Miyaura reactions of tetrabromothiophene, tetrabromo-N-methylpyrrole, and tetrabromoselenophene, respectively. Transition metal-catalyzed cross-coupling reactions of tetrabromo- and ...
