Dependence of the reactivity of five-membered aromatic heterocycles on their structure. 2. Effect of aza substitution on the proton affinity of aminofurans

Abstract

The proton affinities of a series of aminofurans and their aza derivatives were calculated by a nonempirical method in the STO-3G basis set. A correlation was established between the proton affinities and the position of the heteroatoms in the ring.
