A number of polymer-attached, or anchored, catalysts of rhodium and ruthenium have been synthesized, and their activities for D 2 exchange with ethanol have been measured. Among the rhodium anchored catalysts, three exhibited specific activity comparable to Wilkinson's catalyst, RhCl(PPh 3 ) 3 . No polymer-attached ruthenium species had specific activities close to that of the active homogeneous catalyst RuCl 2 (PPh 3 ) 3 . Conditions for the synthesis and optimum loading of complexing resins are discussed. Structural and kinetic comparisons are made between anchored catalysts and their homogeneous analogs.
