Hydrosilylation of norbornene with trichlorosilane in the presence of palladium catalyst (0.01–0.1 mol %) coordinated with (R)-MOP ligand gave a quantitative yield of exo-2-trichlorosilylnorbornane, which was oxidized with hydrogen peroxide to give (1S,2S,4R)-exo-2-norbornanol in 96% ee. The similar hydrosilylation and oxidation of endo-5,6-dicarbomethoxy-2-norbornene, bicyclo[2.2.2]octene, and norbornadiene
在钯催化剂(0.01–0.1 mol%)与(R)-MOP配位体配位的情况下,降冰片烯与三氯硅烷的硅氢加成反应得到定量的exo -2-三氯甲硅烷基降冰片烷,然后用过氧化氢氧化得到(1 S,2 S,4 R)-exo -2-降冰片醇含量为96%ee。内-5,6-二苯甲氧基-2-降冰片烯,双环[2.2.2]辛烯和降冰片二烯的类似氢化硅烷化和氧化反应分别得到相应的双环醇,分别为94%ee,92%ee和95%ee。
