摘要： 本工作研究了带含氧冠醚、氮杂冠醚、酚醛型冠醚、开链冠醚的四种聚合物作为三相催化剂在氰代、碘代和二氯卡宾反应中的催化活性,其中以冠醚环上带有叔胺氮原子的氮杂冠醚聚合物催化活性最好。
Abstract: Catalytic characteristics of four types of triphase catalysts: polymericcrown ethers (A), polymeric azacrown ethers(B),modified phenol formaldehyderesin containing benzo-15-crown-5 (C) and crosslinked acyclic polypode po-lyethers (D) in the cyano-and iodo-substitutions and the addition reactionof dichlorocarbene to styrene were studied. The catalytic activity of polymerswas found in following sequence: (B) (with>NR in the ring)>(A)>(C)>(D)>(B) (with>NH in the ring). The best one among the polymeric cata-lysts studied is that containing azacrown ether with N-alkyl group.
