Figure 8. Cationic intermediate is unlikely in our Cu-catalyzed reaction, based on inverted reactivity of a cationic probe Given the likely intermediacy of a discrete alkyl copper species in this Cu-catalyzed elimination, we questioned if incorporation of a D-atom at the ε carbon would exhibit...
Abstract The ever-increasing demand for efficient and sustainable catalytic systems has prompted a surge in the exploration of transition metal nanoparticles as catalysts for various chemical reactions. Among these, copper-based nanoparticles have emerged as promising contenders, offering a viable alternative...
The cycloaddition catalyzed by GO-CuPc can be considered mild as the reaction is carried out at a pressure below 3 MPa. Especially, a 98% PC yield can be achieved at 1.5 MPa CO2 pressure (Fig. 4c). PC yield is also related to the concentration of GO-CuPc and TBAI, reaching nearly ...

Although it is difficult to clarify the precise mechanism underlying a copper-catalyzed reaction, for convenience, we classified the copper-catalyzed difunctionalization of CC multiple bonds into three types according to the expected role of the copper catalysts in the first bond-formation step (Scheme...
