Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 53911-68-5, Name is 4-(4-Chlorophenyl)dihydro-2H-pyran-2,6(3H)-dione, molecular formula is C11H9ClO3. In a Patent，once mentioned of 53911-68-5, Electric Literature of 53911-68-5
The present invention relates to cinchona-based bifunctional organocatalysts and methods for preparing chiral hemiesters using the same. More specifically, the present invention relates to methods for preparing chiral hemiesters from prochiral or meso cyclic acid anhydrides via desymmetrization, using bifunctional cinchona alkaloid catalysts comprising sulfonamide functional groups.
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 53911-68-5 is helpful to your research., Electric Literature of 53911-68-5
