Isotopic exchange and racemization of some tris-β-diketonato complexes of typical elements of Groups III and IV
1974
Pure and Applied Chemistry
In organic solvents the isotopic exchange between ß-diketone-14 C and its tris complexes with Al 111 , GaiD and Inm proceeds at a greater rate in the order given, and with decrease in pK 11 of the Iigand. There seems to be a rapid equilibrium between the complex and an intermediate with one of the ligands as unidentate, and the break of the remaining bond appears to be the rate 5 determining step. Similar tris:complexes of Sirv and GeiV give an immeasurably slow rate of such an exchange up to
