Abstract
Effects of solvent change on the ^(15)N resonance positions for p-n-butylbenzenediazonium tetrafluoroborate are small. In contrast, the influence of substituents on the ^(15)N chemical shifts for para-substituted benzenediazonium tetrafluoroboratea in acetonitrile are relatively large. For the p-n-butylbenzenediazonium cation in dichloromethane, replacement of the tetrafluoroborate anion by chloride produces small downfield shifts of the ^(15)N resonance positions for both nitrogens. Complexation of benzenediazonium tetrafluoroborates by 18-crown-6 in N,V-dimethylformamide induces relatively large changes in the ^(15)N chemical shifts. Attempts to detect crown ether complexation of other species with diazonium-like termini by ^(15)N NMR were unsuccessful.
