A static and dynamic NMR study of 10-hydrazino-BODIPY

10-Hydrazino-BODIPY, BoNHNH2, presents slow rotation about the C10–NH bond that results in anisochronous 1H and 13C NMR signals. The assignment of the different signals has been made using traditional two-dimensional methods as well as spin–spin coupling constants and confirmed by DFT calculations (...

Descrição
Resumo:10-Hydrazino-BODIPY, BoNHNH2, presents slow rotation about the C10–NH bond that results in anisochronous 1H and 13C NMR signals. The assignment of the different signals has been made using traditional two-dimensional methods as well as spin–spin coupling constants and confirmed by DFT calculations (B3LYP) using the 6-311++G(d,p) basis set. The rotational barrier has been determined in three pairs of proton signals and compared with the calculated barrier.
