The behavior of (pyrrol-1-yl)furazans in electrophilic substitution reactions (halogenation, nitration, and acylation) was studied. The presence of the furazan ring substantially did not affect the regioselectivity of the reactions but it prevented replacement of all the hydrogen atoms in the pyrrole ring by electrophiles.
