Microwave irradiation of aryl bromides and potassium phenyltrifluoroborate in the presence of catalytic Pd(OAc)2 and excess K2CO3 in methanol produces biaryls. This method – a modification of Molander's protocol1 - provides a rapid entry into biaryls by reducing reaction times from hours to minutes and, in many cases, the product precipitates from the reaction medium.
