Elimination reactions of aryl esters of arylacetic acids 1 and 2 promoted by R2NH in MeCN have been investigated kinetically. The reactions are second-order and exhibit β = 0.44−0.84, |βlg| = 0.41−0.50, and ρH = 2.0−3.6. Bronsted β and |βl

Elimination reactions of (E)-O-p-nitrophenyl-2,4-dinitrobenzaldoxime promoted by triethylamine in MeCNH2O proceeded by the E2 mechanism. The rate decreased as the mole % of MeCN increased up to 70 % and then increased upon further increase in the
