In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Recommanded Product: 32005-36-0, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 32005-36-0, name is Bis(dibenzylideneacetone)palladium. In an article，Which mentioned a new discovery about 32005-36-0
Bis-doenes 4 react with distannanes 1, disilanes 2, and silylstannanes 3 in the presence of a catalytic amount of a palladium complex to afford carbocyclization-distannylation, -disilylation and -silastannylation products in high yields.Reaction of distannanes 1a, b with bis-dienes 4a, b as well as reaction of disilane 2b with bis-diene 4d proceeded regio- and stereo-selectively to afford a single product: trans-(E),(Z) isomers.Regio and stereo-selective reaction was also realized with the disilane 2b and bis-diene 4e to provide only trans-(E),(E) isomer.In other cases, the reactions proceeded regioselectively, but the stereoselectivity was modest.The X-ray crystal structures of the cyclopropanes 10 and 11 have been determined.
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 32005-36-0, help many people in the next few years.Recommanded Product: 32005-36-0
