Reactivity of thieno[2,3-b] pyridine towards electrophilic substitution
Abstract
A kinetic study of hydrogen exchange and nitration in thieno[2,3-b]pyridine permitted evaluation of standard rate constants for reaction of the protonated species. Comparison of these results with reactivities of quinoline benzo[b]thiophen, and other heteroaromatic compounds is made in terms of electronic effects of the heteroatoms.
