Application of 1530-32-1In 2022 ,《Catalytic, contra-Thermodynamic Positional Alkene Isomerization》 was published in Journal of the American Chemical Society. The article was written by Occhialini, Gino; Palani, Vignesh; Wendlandt, Alison E.. The article contains the following contents:
The discovery of a dual catalyst system that promotes contra-thermodn. positional alkene isomerization under photochem. irradiation, providing access to terminal alkene isomers, e.g., (2-methylallyl)benzene directly from conjugated, internal alkene, e.g., (2-methylpropenyl)benzene starting materials was reported. The utility of the method is demonstrated in the deconjugation of diverse electron-rich/electron-poor alkenes and through strategic application to natural product synthesis, e.g., (-)-nopinone. Mechanistic studies are consistent with a regiospecific bimol. homolytic substitution (SH2′) mechanism proceeding through an allyl-cobaloxime intermediate. The experimental process involved the reaction of Ethyltriphenylphosphonium bromide(cas: 1530-32-1Application of 1530-32-1)
Ethyltriphenylphosphonium bromide(cas: 1530-32-1) is a phase transfer catalyst, used to accelerate the cure of phenolic-based epoxy resins, certain fluoroelastomer resins and thermosetting powder coatings. CatOnium ETPB is also used as catalysts in the synthesis of certain organic compounds.Application of 1530-32-1
