Abstract: Copper oxide (CuO) nanoparticles (NPs) were prepared through a biological procedure where the Rosa canina fruit extract was used as a capper and reductant agent. For the three-component reaction of amines, aldehydes and alkynes (A3 coupling), these CuO NPs were used as an effective heterogeneous nanocatalyst. Various propargylamines were obtained in a good yield. Additionally, the reuse and separation of CuO NPs was extremely effective, economical and simple.

Ultra-small Au nanoparticles (Au NPs) were immobilized on HS-functionalized sandwich-like periodic mesoporous silica (PMS) coated graphene (G) to form the novel nanocomposite catalyst Au NPs@HS-G-PMS. The synthesized Au NPs@HS-G-PMS nanocatalyst exhibited excellent catalytic activity in three kinds of organic reactions. The reduction of 4-nitrophenol by sodium borohydride, the Suzuki-Miyaura cross coupling reaction of aryl halides with phenyl boronic acid and the three component coupling reaction of aldehyde, alkyne, and secondary amine (A3-coupling) in water were all successfully accomplished. Most importantly, the catalyst could be used repetitively more than six times without significant deactivation.

Due to their high variability and extraordinary features, the MOF-based nanomaterials are regarded as promising photocatalysts in organic reactions. In this study, the magnetic Co-MOF-based nanocomposite (denoted by Cys-CoFe/HK) was prepared through a facile sonochemical method. The composite design was based on the integration and synergy of the desired properties of the components, i.e., optical properties of the magnetic substrate and its separation capability, desirability of metal-organic framework to promote A3-coupling reaction, and use of cysteine ??amino acid as a natural modifier to modify nanoparticles and make an efficient charge transfer. The information about their structural features was obtained using various characterization methods. In addition to the high photocatalytic activity of the developed composite in the aerobic oxidative propargylic functionalization of styrene under visible light illumination, the composite showed a high capability to interact with a wide range of amines, styrene, and terminal alkynes as participants in A3-coupling reaction. Furthermore, the developed catalyst demonstrated high accessibility of active sites, reusability, and magnetic properties, which accelerated the efficiency of the A3-coupling reaction. Moreover, the mechanistic investigations, including trapping experiments, confirmed the presence of superoxide radical (O2●[sbnd]) and holes (h+) as essential species to perform the considered reaction. Our methodical approach to the fabrication of Cys-CoFe/HK composite provided optimal conditions for improving previous studies and thus the industrial processes in environmentally sensitive areas.
