Substituent Effects on 13C and 15N Chemical Shifts in Triazenes Studied by Principal Components Multivariate Data Analysis
Principal components analysis was applied to the 13C and 15N chemical shift data on a series of fifteen 1-(para-substituted-phenyl)-3-acetyl-3-methyltriazenes.It was found that the halogen-substituted triazenes formed a class, based on substituent effects, which was different from the remaining eleven triazenes.A one-component model described the halogen class, whereas a two-component model was necessary for a description of the second class.In the second class, substituent tended to cluster to form groups depending on their electronic character.
