Abstract

One of the most general systems for the cross-coupling of aryl and heteroaryl bromides and chlorides with 2-pyridyl-derived nucleophiles has been developed, for which catalysts comprising [Pd2(dba)3] and either diaryl (1) or dialkyl phosphine oxide (2) supporting ligands were found to be ideal (see scheme).
