Abstract
Divinylbenzene cross-linked chloromethylated polystyrene has been functiona lised with cinchonine, ephedrine, 3S,4S-N-benzylpyrrolidinediol and four ac hiral amines. The resins have been used as supports for anchoring [Rh(CO)(2 )Cl-2](-). The polymer-supported complex has been tested as a catalyst prec ursor for the hydrogenation of alpha-acetamidocinnamic acid. Highest rate a nd modest enantioselectivity are obtained with cinchonine functionalized po lymer-supported complex. This complex also undergoes reversible decarbonyla tion.
