用辛可宁、麻黄碱、3S，4S-N-苄基吡咯烷二醇和四种无手性胺对二乙烯苯交联氯甲基化聚苯乙烯进行官能化。该树脂已被用作锚定[Rh(CO)(2)Cl-2](-)的载体。这种聚合物支撑的络合物已被测试为α-乙酰氨基肉桂酸加氢的催化剂前体。辛可宁官能化聚合物支载络合物的反应速率最高，对映体选择性适中。该络合物还经历了可逆的脱羰基反应。(C)2000由爱思唯尔科学公司出版，版权所有。
Divinylbenzene cross-linked chloromethylated polystyrene has been functionalised with cinchonine, ephedrine, 3S,4S-N-benzylpyrrolidinediol and four achiral 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 precursor for the hydrogenation of alpha-acetamidocinnamic acid. Highest rate and modest enantioselectivity are obtained with cinchonine functionalized polymer-supported complex. This complex also undergoes reversible decarbonylation.
