In heterogeneous catalysis, the catalyst is in a different phase from the reactants. SDS of cas: 52409-22-0, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 52409-22-0, name is Pd2(DBA)3. In an article£¬Which mentioned a new discovery about 52409-22-0
Palladium Nanoparticle-Catalyzed Stereoretentive Cross-Coupling of Alkenyl Sulfides with Grignard Reagents
Reaction conditions allowing a stereoretentive cross-coupling of alkenyl sulfides with Grignard reagents using ligand-free Pd catalysis are discussed here. The presence of an adequately positioned OH function is a key feature that allows a Mg-promoted Lewis acid activation of the mercaptide leaving group. This easy to implement procedure actually relies on an in situ generation of stable Pd nanoparticles by simply mixing Pd2(dba)3, the Grignard reagent, and the vinyl sulfide cross-coupling partner in THF. The efficiency of this procedure has been demonstrated in a natural product total synthesis context.
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 52409-22-0, help many people in the next few years.SDS of cas: 52409-22-0
