- ItemDiolefin rhodium(I) complexes with tropolone and related ligands(1981) Valderrama Guerrero, Mauricio; Rafart, Horacio; Oro, Luis A.Rhodium(I) tropolonate and salicylaldehydate complexes of the general formula Rh(A)(diolefin) (A = tropolonate, ?-iso-propyltropolonate, ?-methyltropolonate and salicylaldehydate; diolefin = 1,5-cyclooctadiene, 2,5-norbornadiene and tetrafluorobenzobarrelene) have been prepared by several routes. The ability of Rh(trop)(COD) to function as an intermediate for the synthesis of other neutral and cationic rhodium(I) complexes has been studied and its hydroformylation activity has been explored briefly.
- ItemRhodium(I) complexes with pyridine-2-aldehyde and related Schiff-base ligands(1983) Oro, Luis A.; Lamata, Mario Pilar; Valderrama Caceres, MauricioThe synthesis of [Rh(TFB)(PyCH=NR)]ClO4 by reaction of the coordinated pyridine-2-aldehyde (PyCHO) moiety of [Rh(TFB)(PyCHO)]ClO4 with primary amines is described. They are active catalysts for the transfer of hydrogen from isopropanol to acetophenone. The catalytic activity depends upon the basicity of the parent amine. Reactions with carbon monoxide and triphenylphosphine give complexes [Rh(CO)2(PyCH=NR)]ClO4, [Rh(CO)(PPh3)2(PyCH=NR)]ClO4 and [Rh(CO)(PPh3)(PyCH=NR)]ClO4.
