“…Cu(0) or CuO-NPs have been employed for catalyzing the synthesis of aryl selenides because of their easy availability, less toxicity, and low cost. For instance, Reddy and coworkers 79 reported that CuO-NPs catalyzed coupling of aryl iodides with diphenyl diselenide to form diaryl selenides under ligand-free conditions in excellent yields (Scheme 6.14).…”

“…A new, efficient, and ligand-free cross-coupling reaction of aryl halides and diaryl diselenides using catalytic amounts of nanocrystalline CuO as a catalyst and with KOH as the base in DMSO at 110 8C was reported by Rao et al [88] This procedure was utilized for the synthesis of a variety of aryl selenides in excellent yields from the readily available aryl halides and diaryl diselenides. In a preliminary experiment, when iodobenzene was treated with diphenyl diselenide in the presence of 2 mol % of CuO nanoparticles and KOH (2.0 equiv) in DMSO (2.0 mL) for 12 h, the corresponding diaryl selenide was obtained in 94 % yield (Table 25).…”

The carbon-carbon and carbon-heteroatom bond formations constitute the backbone of organic synthesis and have been widely used in the synthesis of natural products and useful compounds. Because of growing environmental concern, more attention has been focussed on the development of greener methods. Copper is environment-friendly and comparatively inexpensive. Although the use of copper salts in catalysis has been known since the last century, this area of research has been less explored compared to other metals, such as palladium, magnesium, and zinc. This review highlights the general features of nanoparticles as catalysts with particular reference to copper and the recent developments in the copper(0) nanoparticle-catalyzed C(aryl)-C(aryl/alkynyl), C(aryl)-N, C(aryl)-O, C(aryl)-S, and C(aryl)-Se bond formations and related reactions. The mechanisms of the reactions have been outlined and discussed with respect to the active catalytic species and possible intermediates. The scope, limitations, and green aspects of the reactions have also been highlighted. The convenient methods of preparation of copper nanoparticles and their characterization are described.

“…CuO as a p-type semiconducting material has received considerable attention due to its wide applications in fields such as gas sensors, magnetic phase transitions, superconductors and photocatalysts [13][14][15][16][17][18][19]. Inspired by enhancement of the properties of nanoparticles through anchoring them onto graphene sheets, researchers have attempted to prepare CuO nanoparticle decorated graphene sheets.…”
