Two types of unprecedented side reactions were identified in the Stille coupling reaction, including the direct C-H stannylation of the α-hydrogen of thiophene and the stannylation of arylbromides with trialkylstannane bromide. These results reveal the major source of enhancements for Stille polycondensation efficiency.
