Application of 1271-51-8, In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. In homogeneous catalysis, catalysts are in the same phase as the reactants. In a document type is Article, and a compound is mentioned, 1271-51-8, name is Vinylferrocene, introducing its new discovery.
The [4+2] cycloaddition reaction of the (dimesitylphosphino)cyclopentadienes 5a,b with N-phenylmaleimide gave the norbornene derivative 9. Its reduction with LiAlH4 produced the N-phenylpyrrolidino-annulated system 10. Treatment with Piers’ borane gave the respective P/B FLP 12 as the major product, which cleaved dihydrogen under mild conditions to yield the phosphonium/hydrido borate product 14. Reaction of the phosphino-norbornene 10 with 2 M equiv. of Piers? borane [HB(C6F5)2] followed by exposure to dihydrogen eventually gave the HB(C6F5)2 adduct 15. This served as a catalyst for the hydrogenation of a series of chalcone derivatives. The system requires a pre-activation period before becoming active for the conjugated enone hydrogenation.
The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis. We will look forword to the important role of 1271-51-8, and how the biochemistry of the body works.Application of 1271-51-8
