Resum:
This thesis includes the results of fundamental research on metallocavitand chemistry. The first project describes the effects produced by constraining the organometallic complex (THF-d8)•Ir(I)•COD into the aromatic cavity provided by Rebek’s octaamide cavitand. The unexpected dynamic behavior of the included organometallic complex led to the detection of surprising examples of supramolecular isomerism. The second project deals with the synthesis of an unprecedented series of pyridyl-decorated self-folding heptaamide cavitands. The coordination of Rh(I)•COD with the cavitand’s series produced a cationic organometallic complexes with different binding geometries. The produced Rh(I)-complexes were tested as catalysts in the hydrogenation of norbornadiene. The third project discloses the design, synthesis and characterization of a new cavitand functionalized with a terpyridine Ru(II)•(H2O) complex with 2-(phenylazo)pyridine as an ancillary ligand. The Ru(II)•(H2O) metallocavitand was used as a catalyst in the epoxidation reaction of olefins and the oxidation of primary alcohols.
