52. The reaction did not proceed without CsF. Concerning the effect of CsF, promotion of the transmetalation step by forming arylfluoroborates would be most likely although participation in the carboxylation step by making fluorocuprate might also be possible. Research is now in progress to elucidate the mechanism including the role of CsF and also of the oxazoline ligand.
