Abstract

Abstract The dissociation constants of substituted 2-(4-nitrobenzoylamino) alkanamides, N- [2-(4-nitrobenzoylamino) alkanoyl] pyrrolidines, and N-alkyl-4-nitrobenzamides have been measured spectrophotometrically in 60 and 80% v/v DMSO. The pK A values of these N- acids are discussed from the point of view of substituents at the acetamide α-carbon atom.
