Hydrosilylation reaction of allyl acetate (AA) with octakis(dimethylsiloxy)octasilsesquioxane [(HSiMe2O)8(SiO1.5)8] was efficiently catalyzed by chloro(1,5-cyclooctadiene)iridium(I) dimer [Ir(μ-Cl)(COD)]2. The effects of the catalyst amounts and the reaction conditions on the conversion and the product selectivity were investigated. [Ir(μ-Cl)(COD)]2 catalyst was also applied to the hydrosilylation
乙酸烯丙酯(AA)用的氢化硅烷化反应octakis(二甲基甲)八倍半硅氧烷[(HSiMe 2 O)8(SIO 1.5)8 ]被氯(1,5-环辛二烯)被有效催化的铱(I)二聚体物[Ir(μ -Cl )(COD)] 2。研究了催化剂用量和反应条件对转化率和产物选择性的影响。[Ir(μ- Cl)(COD)] 2催化剂也被用于AA与其他氢硅烷的硅烷化反应,例如五甲基二硅氧烷,1,1,3,3-四甲基二硅氧烷,八氢硅倍半硅氧烷,三乙氧基硅烷和三(三甲基硅氧基)硅烷比较它们的结构-反应关系。
