Abstract
The magnitude of the α-effect for reactions of 4-nitrophenyl substituted benzoates with a pair of anionic nucleophiles is independent of the electronic nature of the acyl substituent, while the one for the corresponding reactions with a pair of neutral nucleophiles increases as the acyl substituent changes from a strong electron withdrawing substituent to electron donating ones. © 2001 Elsevier Science Ltd.
