- ItemRhodium(I) diolefin complexes with polycyclic π-arene ligands. Synthesis of bimetallic complexes with diphenylmethane as bridging ligand(1984) Valderrama Guerrero, Mauricio; Scotti Radich, Mario; Cifuentes, Pedro; Ganz, RicardoThe preparation and properties of cationic arenerhodium(I) complexes of general formula [Rh(diolefin)(?6arene)]ClO4 (diolefin=1,5-cyclooctadiene, tetrafluorobenzobarrelene or trimethyltetrafluorobenzobarrelene; arene = biphenyl or diphenylmethane) are described. These complexes react with the solvated intermediate complex [Rh(diolefin)(Me2CO)x]ClO4 to give homobimetallic [(diolefin)Rh(Ph2CH2)Rh(diolefin)](ClO4)2 derivatives. New heterobimetallic complexes of the type [(diolefin)Rh(Ph2CH2)Cr(CO)3]ClO4 have been synthesized by reaction of Cr(CO)3(?6-Ph2CH2) with the solvated complex [Rh(diolefin)(Me2CO)x]ClO4 or, alternatively by treatment of [Rh(diolefin)(?6-arene)]ClO4 with the complex Cr(CO)3(?6Me3B3N3Me3) in chloroform solution.
- ItemSynthesis and reactivity of cationic trimethyltetrafluorobenzobarrelene rhodium(I) complexes(1983) Valderrama Guerrero, Mauricio; Ganz, Ricardo; Sariego, RenatoThe preparation and properties of cationic rhodium(I) complexes of the types [Rh(Me3TFB)L2]PF6 (L=O. N. P, As or Sb-donor ligands, Me3TFB=trimethyltetrafluorobarrelene), [Rh(Me3TFB) (?6-arene)]PF6 (arene=C6Me6, C6H6Me3, C6H6 or C10H8) and [Rh(Me23TFB)(PPh3)L]PF6 (L=Me2CO or Me2SO) are described. Some complexes react with carbon monoxide at normal pressure with displacement of Me3TFB and formation of carbonyl derivatives. The arene-exchange behaviour for the new complex with naphthalene (C10H8) was examined in acetone solutions.
