Electric Literature of 127956-11-0, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 127956-11-0, Name is Methyl 4-oxotetrahydro-2H-pyran-3-carboxylate, molecular formula is C7H10O4. In a Article，once mentioned of 127956-11-0
A chiral guanidinium ion is shown to catalyze enantioselective Claisen rearrangements of O-allyl beta-ketoesters in 78-87 % ee (see scheme). The pericyclic nature of the process allows products containing vicinal stereogenic centers to be accessed with both enantio- and diastereocontrol. Copyright
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 127956-11-0 is helpful to your research., Electric Literature of 127956-11-0
