Metal and Metal Oxide Nanoparticles Catalyzed C-H Activation for C-O and C-X (X = Halogen, B, P, S, Se) Bond Formation

The direct functionalization of an inactivated C-H bond has become an attractive approach to evolve toward step-economy, atom-efficient and environmentally sustainable processes. In this regard, the design and preparation of highly active metal nanoparticles as efficient catalysts for C-H bond activation under mild reaction conditions still continue to be investigated. This review focuses on the functionalization of un-activated C(sp3)-H, C(sp2)-H and C(sp)-H bonds exploiting metal and metal oxide nanoparticles C-H activation for C-O and C-X (X = Halogen, B, P, S, Se) bond formation, resulting in more sustainable access to industrial production.
