In heterogeneous catalysis, the catalyst is in a different phase from the reactants. SDS of cas: 185812-86-6, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 185812-86-6, name is Di-mu-Bromobis(tri-tert-butylphosphine)dipalladium. In an article£¬Which mentioned a new discovery about 185812-86-6
Oxygen Activated, Palladium Nanoparticle Catalyzed, Ultrafast Cross-Coupling of Organolithium Reagents
The discovery of an ultrafast cross-coupling of alkyl- and aryllithium reagents with a range of aryl bromides is presented. The essential role of molecular oxygen to form the active palladium catalyst was established; palladium nanoparticles that are highly active in cross-coupling reactions with reaction times ranging from 5 s to 5 min are thus generated in situ. High selectivities were observed for a range of heterocycles and functional groups as well as for an expanded scope of organolithium reagents. The applicability of this method was showcased by the synthesis of the [11C]-labeled PET tracer celecoxib.
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 185812-86-6, help many people in the next few years.SDS of cas: 185812-86-6
