suggest the detailed mechanisms. All the β-lactams appear to react with rate-determining addition of hydroxide anion; while the N-alkyl γ- and δ-lactams and N-alkyl-N-methylacetamides have rate-determining ring fission of the tetrahedral adduct, assisted by water-catalysis. The reactivity of penicillin in alkalinehydrolysis has been analysed by the studies of model compounds. These show that the increased
