✦ Synopsis

AbstractÐThe study of the effect of a condensed ring on the reactivity of nitrosoimidazoles with hydrochloric acid has been extended to some six-membered rings: thus, the reactivity of 2 9) has been examined. The striking differences observed in the reactivity of compounds 6±9 (denitrosation, ringopening with ammonia elimination, ring±ring interconversion with the unexpected loss of a C 3 fragment and decomposition, respectively) have been discussed.
