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).
Billingsley et al. (Mon,) studied this question.
