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.

Iridium-catalyzed regiospecific and stereospecific allylic amination for the syntheses of alpha,beta-unsaturated gamma-amino esters and the bifurcation of the reaction pathway leading to the formation of oxazolidin-2-ones
A pair of iridium-catalyzed regiospecific and stereospecific reactions of the carbonates of gamma-hydroxy alpha,beta-unsaturated esters were developed. The reaction pathways are strongly affected by the choice of amines employed. A diverse range of gamma-substituted alpha,beta-unsaturated gamma-amino esters were prepared in excellent yields with various amine nucleophiles such as benzylamine, diallylamine, morpholine, aniline and N-methylaniline. Substitution at the gamma-position was well tolerated, encompassing alkyl, aryl and heteroaryl substituents. Enantioenriched (E)-alpha,beta-unsaturated gamma-amino esters could also be synthesized from the corresponding enantioenriched allylic carbonates with complete chirality transfer. In sharp contrast, a series of 3,4-disubstituted oxazolidin-2-ones were obtained by using allylamine as a nucleophile.
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
