A highly efficient synthetic method for the preparation of 2-aminobenzothiazoles starting from arylthioureas has been reported. By using a nickel catalyst, arylthioureas undergo intramolecular oxidative C-H bond functionalization, giving the desired 2-aminobenzothiazoles in good to excellent yields. This protocol features an inexpensive catalyst, low catalyst loading, mild reaction conditions, a short reaction time, and good to excellent yields, and it can be scaled up easily to a gram scale with almost no yields decreasing.

A facile and efficient formation of 2-aminobenzothiazoles by a copper(II)-promoted one-pot cascade process was developed. The desired 2-aminobenzothiazoles were synthesized in good to excellent yields (up to 97 %) in the presence of Cu(OAc)2 an
