The preparation and properties of rhodium complexes of the general formulae Rh(A)(CO)2 and Rh(A)(CO)L (A=tropolone (trop), Me-trop, i-Pr-trop, salicylaldehyde (sal) are described.The coordinated salicylaldehyde moiety of (Y2=COD, (CO)2, (CO)PPh3) complexes react with primary amines to yield Rh(sal=NR)Y2 derivatives.Rh(sal=NMe)(CO)2 can be formed by addition of salicylaldehyde to the solution obtained by refluxing RhCl3*xH2O with dimethylformamide.
