Syntheses, characterization and catalytic activities of CaAl-layered double hydroxide intercalated Fe(III)-amino acid complexes

Catalytic use of layered materials for fine chemical syntheses

“…In both reactions, the oxidant was iodosylbenzene [PhIIJOH) 2 ] in situ formed from (diacetoxy)iodobenzene (Scheme 13). 67 Recently, composites have been prepared where CaAl-LDH was the host and the anionic forms of MnIJII)-, 68 CuIJII)-, 69 Fe (III)- 70 and NiIJII)-amino acid (L-histidine, L-tyrosine, L-cysteine) 71 were the guests. The composites were tested in the oxidation reactions of cyclohexene and two oxidants (peracetic acid and PhIIJOH) 2 ) (Scheme 14).…”

“…The CuIJII)-, 69 the FeIJIII)- 70 and MnIJII)-containing 72 composites were probed in the Ullmann-type etherification (Scheme 15), 73 and they were found to be efficient catalysts in these transformations, too. The composites also displayed very good recycling abilities.…”
