heteroaryltrifluoroborates in Suzuki-Miyaura cross-coupling reactions is presented. The coupling of aryl- and electron-rich heteroaryltrifluoroborates with aryl and activated heteroarylbromides proceeds readily under ligandless conditions. When deactivated aryl- and heteroaryltrifluoroborates are coupled with aryl and heteroarylbromides and chlorides, a low loading (0.5-2%) of PdCl(2)(dppf).CH(2)Cl(2) efficiently
