Furyl groups substituent constants

Nitrile-forming eliminations from 2,4,6-trinitrobenzaldehyde 0-oxime derivatives promoted by amines in MeCN have been studied kinetically. The reactions are second-order and exhibit substantial Hammett p and Brpnsted ft values. The second-order rate constant for elimination from ( )-2,4,6-trinitrobenzaldehyde 0-pivaloyloxime promoted by /-Pr2NH in MeCN falls on a single line in the Hammett plot for different j0-aryl substituents, which have been shown to react by the E2 mechanism. The change of the /3-aryl group from phenyl to thienyl to furyl shifted the reaction mechanism from E2 to ElcE) f ... [Pg.361]
