Abstract

Abstract A considerable effort in ligand design for catalysis in recent years has led to remarkable achievements in cross-coupling reactions. In this work, we show that a careful selection of the ancillary ligands that complete the catalyst/precatalyst can provide an extra level of performance. Low loadings of [(IPr*) PdCl 2 (TEA)]{IPr*= 1, 3-bis [2, 6-bis (diphenylmethyl)-4-methylphenyl] imidazole-2-ylidene, TEA= triethylamine} catalyze the ...
