Abstract
The preparation and properties of cationic arenerhodium(I) complexes of general formula [Rh {P(OMe)3}(?6-arene)]A [arene=C6H6?nMen (n=0, 1, 2, 3, 4 or 6); A=ClO 6? , PF 6? ] are described. The coordinated arene is dissociated in (CD3)2 CO or DCCl3 solution and this dissociation decreases with increased methyl substitution of the arene ligand.
The ability of these cationic complexes to function as an intermediate for the synthesis of other rhodium(I) complexes by displacement of the coordinated arene with ? or ?-donor ligands has been studied.The preparation and properties of cationic arenerhodium(I) complexes of general formula [Rh {P(OMe)3}(?6-arene)]A [arene=C6H6?nMen (n=0, 1, 2, 3, 4 or 6); A=ClO 6? , PF 6? ] are described.
