The effects of adding various cyclodextrins (α-,β- and γ-cyclodextrin) on the redox reaction between N-alky1-1, 4-dihydronicotinamide (hydride ion donnor) and ninhydrin (hydride ion acceptor) in aqueous solutions were studied kinetically. These reactions proceed through the hydride ion donnor-acceptor complex (CT complex) formation without cyclodextrin (CD). The presence of CD especially affects the reduction with N-benzy1-1,4-dihydronicotinamide (BNAH). β-CD is most effective for decreasing the reduction rate in three CDs. β-CD inhibited the formation of the CT complex by including BNAH molecule, which caused a decrease in the reaction rate. β-CD also completely inhibited the hydration of BNAH. γ-CD also included BNAH, however, it had little effect on the reduction rate constant. α-CD had no effect on both the reduction and the hydration. These inhibition behaviors were caused by an inclusion complex formation with CD.
