“…1494 In sharp contrast, Chatani disclosed a protocol for the C−H amination of 2-phenylpyridines 24 with anilines 137 by means of copper catalysis (Scheme 689b). 1672 After these early reports, several protocols have been developed for the directed-amination of 24 with different amine sources using catalytic quantities of copper. 1673−1677 Furthermore, such C− H aminations have been studied with well-defined copper(III) complex as well.…”

C−H activation has surfaced as an increasingly powerful tool for molecular sciences, with notable applications to material sciences, crop protection, drug discovery, and pharmaceutical industries, among others. Despite major advances, the vast majority of these C−H functionalizations required precious 4d or 5d transition metal catalysts. Given the cost-effective and sustainable nature of earth-abundant first row transition metals, the development of less toxic, inexpensive 3d metal catalysts for C−H activation has gained considerable recent momentum as a significantly more environmentally-benign and economically-attractive alternative. Herein, we provide a comprehensive overview on first row transition metal catalysts for C−H activation until summer 2018.

“…The copper catalysis in aerobic condition was used in the amination of heterocyclic inactive sp 3 C-H in presence of K2CO3. The aerobic cross-coupling of heterocyclic ( 13) with nucleophiles would lead to the 2-amido-substituted heterocyclic (14) through the organocopper intermediate (15) in analogy to the Chan-Lam oxidative coupling of arylboronic acids and nucleophiles [73][74][75][76][77][78][79][80][81][82][83].…”

Over the last few decades, signiﬁcant efforts have been put forth towards the C−H bond group functionalization by transition-metalcatalysis and organocatalysis. Several efficient strategies to convert C-H bond to other groups C-C, C-N, C-O bonds have been implemented. The most attractive C-H bond functionalization was the C-H heterocyclic compounds activation that is practical method in organic synthesis. The new C–C, C–N and C–O bond as formed from the C-H bond activation by two diverse ways metal catalysis and/or organocatalysis. The most important is the synthesis of new bioactive heterocyclic compounds by easy and less expensive materials. In this review, we will cover most of the syntheses of heterocyclic derivatives by the functionalization of C-H bond in metal and organocatalytic reagents.
