Abstract

The acid catalyzed hydrolysis of two N-substituted hydroxamic acids (C6H5CON(OH)R′, R′ = C6H5 (PBHA), R′ = C6H5CH2(BBHA)) in mixed systems containing β-cyclodextrin (β—CD) and a surfactant (sodium dodecyl sulfate, SDS) has been studied. The reactions are inhibited by β—CD. The inhibition is attributed to the formation of inclusion complex and competition between the micellization and complexation processes.
