Palladium-catalyzed electrophilic C–H fluorination of arenes using oxazoline as a removable directing group

2016 
Abstract Dimethyloxazoline was rationally designed to act as a removable ortho -directing group (DG) for the palladium-catalyzed C–H electrophilic fluorination of arenes. Using NFSI as the fluorinating agent, and Pd(II), Ag(I) catalytic system, electrophilic C(sp 2 –H) ortho -fluorination took place on a variety of aryl substrates to afford the corresponding mono- and di-fluorinated products.
