Phthalocyanine Ring

Substituted iron and cobalt phthalocyanines are easily prepared by microwave irradiation of the starting materials under solvent free condition, which reduced reaction time considerably. The synthesized metallophthalocyanines (octachloro-, tetranitro-, tetracarboxy- or polyphthalocyanine) are used as epoxidation catalysts of cyclooctene in homogeneous and heterogeneous conditions by iodosylbenzene as an oxidant. Their catalytic activities have shown that the electron withdrawing groups on the phthalocyanine ring have a very small effect on stability of the catalyst during the reactions.

Work Up

The synthesis of Fe-MIL-101 material with the presence of H2BDC linker and iron (III) chloride achieving remarkable success is a result of solvothermal method. Catalytic activity works on the Friedel-Crafts benzoylation reaction of aromatic compounds and benzoyl chloride. In addition, Fe-MIL-101 is a heterogeneous catalyst which succeeds in not only shortening duration in a significant amount, but also increasing conversion with the assistance of the microwave irradiation compared with the conventional heating. Fe-MIL-101 would be a very potential alternative in place of unfavourable and dated iron (III) chloride homogeneous catalyst, due to its thermal stability, moreover, it can be recovered and reused after aqueous work-up.

Friedel-Crafts acetylation is an important reaction in organic synthesis processes. Acetylation of indole derivatives with acetic anhydride as acylating reagent using Cu(OTf)2 as a catalyst has been investigated under microwave irradiation. Different from traditional Lewis acidic catalyst, Cu(OTf)2 was found to be an efficient catalyst for Friedel-Crafts acetylation of indoles under mild conditions. Moreover, Cu(OTf)2 was safe-to-handle, recovered and reused several times without significant loss of catalytic activity.
