2-carbonyl substituted phenolicderivatives or 1,3-diketo derivatives with N,N-disubstituted formamides (C(sp2)O bond formation) under mild conditions is the key focus of synthetic chemists. In this context, we have developed a novel benzothiazole appended 2,6-di picolinamide-based Cu(II) complex for the facile generation of carbamates at a slightly elevated temperature (50°C) with a short reaction

An efficient ruthenium(II)‐ and palladium(II)‐catalyzed CH hydroxylation of aryl carbamates has been developed for the facile synthesis of catechols and pyrogallols. The reaction demonstrates excellent reactivity, regio‐ and chemoselectivity, good functional group compatibility and high yields. The practicality of this method has been proved by a gram‐scale synthesis.
