摘要：

Suzuki-Miyaura coupling reactions are promoted by Pd complexes ligated with C-2-symmetric multi-dentate N-heterocyclic carbenes derived in situ from Pd(OAc)(2) and imidazolium salts. Good to excellent yields were obtained for aryl bromides as substrates. Turnover numbers of up to 10(5) could be achieved with 5 x 10(-4) mol% of Pd(OAc)(2)/1 x 10(-3) mol% NHC precatalyst in 24 h.
