Milner, Phillip J.; Yang, Yang; Buchwald, Stephen L. published the artcile< In-Depth Assessment of the Palladium-Catalyzed Fluorination of Five-Membered Heteroaryl Bromides>, Safety of 4-Bromo-3-phenyl-1H-pyrazole, the main research area is palladium catalyzed fluorination five membered heteroaryl bromide; bromoazole palladium catalyzed fluorination theor.

A thorough investigation of the challenging Pd-catalyzed fluorination of five-membered heteroaryl bromides is presented. Crystallog. studies and d. functional theory (DFT) calculations suggest that the challenging step of this transformation is C-F reductive elimination of five-membered heteroaryl fluorides from Pd(II) complexes. On the basis of these studies, we have found that various heteroaryl bromides bearing Ph groups in the ortho position can be effectively fluorinated under catalytic conditions. Highly activated 2-bromoazoles, such as 8-bromocaffeine, are also viable substrates for this reaction.
