A general synthesis of alpha-trifluoromethylstyrenes through palladium-catalyzed cross-couplings with 1,1,1-trifluoroacetone tosylhydrazone
1,1,1-Trifluoroacetone tosylhydrazone is presented as a very convenient substrate for the palladium-catalyzed cross-coupling with aryl halides. Under the proper reaction conditions, 3,3,3-trifluoromethylstyrenes – very valuable trifluoromethylated synthetic intermediates – are obtained with high yields. The reaction features a very wide scope, as the presence of most functional groups is tolerated. Moreover, the reaction has been extended to substituted trifluoromethylstyrenes by employing substituted tosylhydrazones derived from other trifluoromethyl ketones.
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 52409-22-0 is helpful to your research. Related Products of 52409-22-0
