In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Quality Control of Tetrakis(acetonitrile)palladium(II) tetrafluoroborate, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 21797-13-7, name is Tetrakis(acetonitrile)palladium(II) tetrafluoroborate. In an article£¬Which mentioned a new discovery about 21797-13-7
Aerobic Pd-catalyzed sp3 C-H olefination: A route to both N-heterocyclic scaffolds and alkenes
This communication describes a new method for the Pd/polyoxometalate- catalyzed aerobic olefination of unactivated sp3 C-H bonds. Nitrogen heterocycles serve as directing groups, and air is used as the terminal oxidant. The products undergo reversible intramolecular Michael addition, which protects the monoalkenylated product from overfunctionalization. Hydrogenation of the Michael adducts provides access to bicyclic nitrogen-containing scaffolds that are prevalent in alkaloid natural products. Additionally, the cationic Michael adducts undergo facile elimination to release alpha,beta-unsaturated olefins, which can be further elaborated via C-C and C-heteroatom bond-forming reactions.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 21797-13-7, help many people in the next few years.Quality Control of Tetrakis(acetonitrile)palladium(II) tetrafluoroborate
