The reactions of 4-(4'-nitrophenyl)-4-X-butan-2-one (1-X; X = Cl, OTs) with added bases/nucleophiles exhibit second-order kinetics. These substitution and elimination reactions are concluded to be of concerted S N 2 type and irreversible E1cB type, respectively. The spontaneous formation of alkene f
