| Popis: | A metal–organic framework functionalized with a cobalt-complex is prepared via post-synthetic modification of Fe-MIL-101-NH2. Initially, Fe-MIL-101-NH2 reacted with isatin to produce Fe-MIL-101-isatin-Schiff-base, which can anchor the cobalt by the addition of cobalt acetate. The resulting MOF-Co catalyst is characterized by employing multiple techniques. This new modified MOF acts as a heterogeneous and recyclable catalyst for efficient Ullmann, Buchwald–Hartwig, Hirao, Hiyama and Mizoroki–Heck cross-coupling reactions of several aryl halides/phenylboronic acid/phenyltosylate with phenols, anilines/heterocyclic amines, triethyl phosphite, triethoxyphenylsilane and alkenes and generates the expected coupling products in good to high yields. Financial support of this project from the University of Birjand Research Council is acknowledged. Access to the FESEM, EDX mapping, TEM and XPS facilities at the Department of Chemistry, University of Alicante, is appreciated. |
