Reference of 4971-56-6, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 4971-56-6, molcular formula is C4H4O3, introducing its new discovery.
This review details the current methods used to prepare vinyl triflates derived from 1,3-dicarbonyl compounds and describes the reactivity of such functionalized vinyl triflates. alpha-Ketovinyl triflates can easily and stereoselectively be produced through three different ways. Enolization and triflation is the most common route, but direct triflation with triflic anhydride could also be used, each involving different mechanisms. Direct addition of triflic acid and related sulfonic acids to triple bond offers an alternative to the previous methods. With their peculiar set of functional groups, alpha-ketovinyl triflates can react in four different ways. The vinyl triflate part could be engaged in coupling reactions, while the carbonyl group as well as the enone motif could be subjected to nucleophilic additions. If a proton is available next to the triflate group, eliminations could occur under basic conditions. Upon addition, fragmentations could also be possible.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 4971-56-6 is helpful to your research. Reference of 4971-56-6
