One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 401566-79-8, Name is 1-(3-Methyl-1-phenyl-1H-pyrazol-5-yl)piperazine, formurla is C14H18N4.

Using the Competing Enantioselective Conversion Method to Assign the Absolute Configuration of Cyclic Amines with Bode’s Acylation Reagents
The competing enantioselective conversion (CEC) method is a quick and reliable means to determine absolute configuration. Previously, Bode’s chiral acylated hydroxamic acids were used to determine the stereochemistry of primary amines, as well as cyclic and acyclic secondary amines. The enantioselective acylation has been evaluated for 4-, 5-, and 6-membered cyclic secondary amines, including medicinally relevant compounds. The limitations of the method were studied through computational analysis and experimental results. Piperidines with substituents at the 2-position did not behave well unless the axial conformer was energetically accessible, which is consistent with the transition state geometries proposed by Bode and Kozlowski. Control experiments were performed to investigate the cause of degrading selectivity under the CEC reaction conditions. The present study expands the scope of the CEC method for secondary amines and provides a better understanding of the reaction profile.
