Add time:07/15/2019 Source:sciencedirect.com
A series Rh(III)-catalyzed ortho-selective C–H halogenation of 2-arylbenzo[d]thiazoles has been developed using N-halosuccinimides (NXS, X=Br and I) as halogen sources. ortho-Brominated and iodinated various 2-arylbenzo[d]thiazoles could be accessed in good to excellent yields and high regioselectivity under mild reaction conditions.
