A mild and green methodology for the construction of N‐(pyridine‐2‐yl)amides from alkylarenes and 2‐aminopyridine in one step was developed. Various alkylarenes were directly transformed into the corresponding N‐(pyridine‐2‐yl)amides through tandem C(sp3)–H bond activation/oxidative cyclization/C–C bondcleavage.

cleavage of C(CO)–C(alkyl) bond to generate N-substitutedbenzamides has been developed in the presence of copper(I) chloride. The usage of inexpensive copper catalyst, broad substrate scope, mild conditions make this protocol very practical. More importantly, this reaction provides an alternative approach for the construction of useful N-substitutedbenzamides.

We report here a simple and efficient copper catalyzed oxidative C–C bond cleavage of stable aromatic cyclic-fused and acyclic 1,2-diketones to deliver amides and imides in high yields. This newly developed protocol provides an excellent tool to transform structurally different 1,2-diketones into different products under the same reaction conditions. The key synthetic features of this methodology are
