One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Recommanded Product: 21797-13-7, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 21797-13-7, Name is Tetrakis(acetonitrile)palladium(II) tetrafluoroborate, molecular formula is C8H12B2F8N4Pd
alpha,alpha?-Disubstituted styrenes undergo a difluorination-rearrangement reaction with fluoro-benzoiodoxole reagent 1. The reaction is catalyzed by Pd(MeCN)4(BF4)2 and Cu(MeCN)4PF6. We have studied the rearrangement of alpha,alpha?-diaryl substituted styrenes, in which the aryl groups have different electronic character. In the case of alpha-aryl, alpha?-alkyl substituted styrenes, the aryl substituent has a higher migratory aptitude than the alkyl group. We have also extended the reactions to cycloalkyl styrenes, which underwent interesting ring contraction/expansion reactions. The regioselectivity of the migration can be explained on the basis of the formation of a phenonium intermediate.
