Abstract

Abstract Principal components analysis was applied to the 13 C and 15 N 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 ...
