摘　　要：3-烯丙基邻苯二酚与氯乙醇反应,得到3-烯丙基-1,2-双羟乙氧基苯,它与二缩三乙二醇双对甲苯磺酸酯反应,得到3-丙烯基苯并18-冠-6。从4-烯丙基邻苯二酚类似地制得4-烯丙基1,2-双羟乙氧基苯。它与1,2-双羟乙氧基苯双对甲苯磺酸酯反应,合成了4-丙烯基二苯并-18-冠-6。二种丙烯基取代冠醚与三氯硅烷反应,以二氧化硅固载化,得到二氧化硅固载苯并冠醚,它们皆可与铂形成配合物,是一类新型烯烃硅氢化催化剂。3-and 4-allyl-1,2-bis (β-hydroxyethoxy) benzene were synthesized from ethylene chlorohydrin and 3-or 4-allyleatechol, respectively. Reacting 3-aUyl-1,2-bis (hydroxyethoxy) benzene with diethylene glycol ditosylate or reacting 4-allyl-1, 2-(hydroxyethoxy) benzene with 1, 2-bis (hydroethoxy) benzene ditosylate, two benzo crown ethers, 3'-propenyl-2, 3-benzo-1,4, 7, 10, 13, 16-hexaoxa-cyclooctadec-2-ene and 4'-propenyl-2, 3, 11, 12-dibenzo-1,4,7, 10, 13, 16-hexaoxa-cy-clooctadeca-2,11-diene ,were obtained. The benzo crown ethers were subjected to hydrosilylation with trichlorosilane,followed by immobilization on silica, to give the title silica-bound benzo crown ethers.The silica-bound benzo crown ethers could coordinate with platinum. The both platinum complexes were found to be an effective catalyst for hydrosilylation of olefins with triethoxysflane.
