Abstract
High-resolution proton-coupled ^(15)N NMR spectra of neat phenylhydrazine (1) have been studied at the natural abundance level over the temperature range of 20-70 ºC. Proton transfer from the -NH_2 group was found to be about two orders of magnitude faster than that from the -NH- group. The ^(15)N chemical shifts of 1 in a variety of basic, neutral, and acidic solvents show that influences of the medium are different for the two types of nitrogens in 1. Proton-coupled ^(15)N spectra of 1 in various solvents confirm the results of the variable-temperature studies. The differential rates of the proton-transfer reactions of 1 can be ascribed to two different bimolecular exchange mechanisms.
