Janus-type homo-, hetero-and mixed valence-bimetallic complexes with one metal encapsulated in a cyclodextrin
Résumé
Bis-azolium salts with one azolium capping a perbenzylated a-cyclodextrin have been designed to generate Janustype bimetallic complexes with various combinations of copper, silver, gold or palladium salts. Encapsulation of one metal center inside the cavity allowed to control (trans)metalation and oxidation reactions at selected positions. In particular, it was possible to oxidize Au I into Au III selectively on the position outside the cavity of the cyclodextrin on the bis-Au I Janus complex.
