ABSTRACT

Proton affinity of furazane, furoxane, and their aminoderivatives for protonation at various centers was calculated by ab initio methods using the STO-3G basis set. Basicity was found to decrease in the following order: N-oxide oxygen atom, endocyclic nitrogen atom, amino group. The presence in the ring of aminogroups or N-oxide functions leads to elevated proton affinity of the basic centers which are located in the active positions of the ring. More... »
