title: Pd-catalyzed β-selective direct C-H bond arylation of thiophenes with aryltrimethylsilanes.
abstract: Direct arylation of thiophenes and benzothiophenes with aryltrimethylsilanes was effectively catalyzed by PdCl(2)(MeCN)(2) in the presence of CuCl(2) as an oxidant. The reaction preferentially occurred at the β-position of both thiophenes and benzothiophenes.
