Pd(II)-catalyzed ortho arylation of 2-arylbenzothiazoles with aryl iodides via benzothiazole-directed C-H activation
A novel and efficient method for the arylation of 2-arylbenzothiazoles is described via C-H activation. The desired CAr-CAr bond formation proceeded efficiently with good functional-group tolerance and high regioselectivity. Proposed
