  Pd(PPh3)4-catalyzed direct ortho-fluorination of 2-arylbenzothiazoles with an electrophilic fluoride N-fluorobenzenesulfonimide (NFSI)

  摘要：

  An efficient protocol was developed for regio-selective Pd-catalyzed direct ortho-fluorination of 2-alylbenzo[d]thiazoles using N-fluorobenzenesulfonimide (NFSI) as the F+ source, and L-proline as the crucial promoter. The present method offered a practical route to synthesize valuable fluorinated products, which are of potential importance in the pharmaceutical and agrochemical industries. (C) 2013 The Authors.

  benzothiazoles or benzoxazoles is reported. This represents a first example of metal-catalyzed decarboxylative C–H heteroarylation of benzo-fused heterocycles. The transformation provides a convenient route, with good yields and functional group tolerance, to various important arylheteroaryl and unsymmetrical biheteroaryl structural motifs.
