Article abstract of DOI:10.1002/aoc.4307

This study demonstrates ED-UiO-66 as a novel and effective solid nanoporous basic catalyst prepared through the amine grafting onto the pores of UiO-66. The manufactured nanoparticles were identified by FT-IR, XRD, TGA, FESEM, TEM, CHN and BET and the characterization results certified formation of a single phase nanoporous substance with the medium grain size less than 90?nm. The synthesized material was employed as an efficient catalyst for the preparation of 2-aminotiophenes through the Gewald method. This thermochemically stable nanocatalyst was environmentally safe, reusable and economic. Therefore, this methodology can be simply extended for industrial goals.
