Half-wave Reduction Potentials of Azomethine Compounds in the Presence of α-Cyclodextrin

Abstract

As one of studies on the effect of proton donor on the half-wave reduction potential, DC polarographic behavior of N-benzylideneaniline (BA) and N- (diphenylrnethylene) aniline (DA) was investigated in DMF solution in the presence of cx-cyclodextrin (CD) by the three-electrode system. The half-wave reduction potential of the 1 at wave shifted to a less negative potential (100-150 mV) by the addition of CD. As a most plausible interpretation on the results, the formation of hydrogen bond was suggested between BA or DA and CD.
