Nitrobenzofurazans and nitro-2,1,3-benzothiadiazoles: unexpected reactivity towards nucleophilic attack
Abstract
The reactivity of 4-chlorobenzofurazan towards methoxide ion is about the same as that of o-nitrochlorobenzene, but the reactivity of 4-chloro-5-nitrobenzofurazan towards the same reagent exceeds that of picryl chloride: other examples of unexpectedly high reactivity of related compounds towards nucleophilic reagents are given.
