Reference of 131833-93-7, In heterogeneous catalysis, the catalyst is in a different phase from the reactants. At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 131833-93-7, name is (4S,4’S)-2,2′-(Propane-2,2-diyl)bis(4-(tert-butyl)-4,5-dihydrooxazole).

Diastereoselective silylene transfer reactions to chiral enantiopure alkenes: Effects of ligand size and substrate bias
Silylenes are useful reactive intermediates for the stereoselective construction of compounds containing carbon-silicon bonds. Despite their synthetic utility, the development of either an enantioselective or diastereoselective metal-catalyzed silylene transfer reaction, in which ligands on the metal catalyst control stereoselectivity, has not been achieved. In this article, we report that the structure of the alkene is the most important for controlling stereoselectivity in these reactions. The stereochemical course of kinetically controlled silacyclopropanation reactions was not affected by the nature or chirality of the ligands on the metal. When silylene transfer reactions were reversible, however, products can be formed with a high degree of diastereoselectivity (90:10 d.r.).
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.131833-93-7. In my other articles, you can also check out more blogs about 131833-93-7
