Identification of 4,5-asymmetrically substituted 1-(N-isoimido)-1,2,3-triazoles by benzene induced shifts in NMR spectra—VII

Proton chemical shifts, as well as solvent shifts induced by benzene, can be used for the structure determination of 4,5-asymmetrically substituted 1-(N-isoimido)-1,2,3-triazoles, derived from the oxidation of α-diketone bisaroylhydrazones. The geometry of the postulated ‘collision complex’ is discussed and an attempt is made to estimate theoretically the induced shifts of some of the protons.
