Polycondensed nitrogen heterocycles. Part21. Complete13C NMR assignment of annelated phenanthridines
Two-dimensional nmr techniques were used for the complete assignment of 13C nmr spectra of pyrrolo-[1,2-f]-, pyrazolo[1,5-f]-, and 1,2,4-triazolo[1,5-f]phenanthridines.
Protonation of 3-aminopyrroles
Abstract The protonation of 3-aminopyrroles has been investigated using H and 13C n.m.r. spectroscopy. The spectral data are compatible with predominant protonation of the amino group with no evidence for protonation of the pyrrole ring.
