Abstract: Bipyridine attached benzofuran derivatives were prepared by the cyclization of alkyne ortho-substituted phenols. Electronically different substituents, N,N-dibutylamino vs tert-butyl group, were attached on benzofuran rings. Depending on the polarity and pH of solvent environment, N,N-dialkylamino… read more here.
