Both catalytic activity and selectivity of Ru(PPh_3)_3Cl_2 were improved in ionic liquid BMImPF_6/DME medium.The conversion of hexene and selectivity ofβ-adduct for the hydrosilylation reaction of 1-hexene with triethoxysilane catalyzed by Ru(PPh_3)_3Cl_2 in ionic liquid BMImPF_6DME (V/V=1/4) medium at 90℃were 100% and 89.0%,respectively.
实验结果表明,在乙二醇二甲醚/离子液体1-丁基-3-甲基咪唑六氟磷酸盐(BMImBF_6)(V/V =1/4)介质中,于90℃下,己烯与三乙氧基硅烷反应的转化率为100%,β加成物的选择性可达89.0%,而用Rh(PPh_3)_3Cl作为反应的催化剂,在纯离子液体BMImPF_6中,就可以高效催化烯烃与三乙氧基氢硅烷的加成反应,过渡金属Rh(PPh_3)_3Cl,Ru(PPh_3)_3Cl_2催化剂/离子液体BMImPF_6催化体系,不仅解决了产物与催化剂分离困难这一难题,同时,离子液体BMImPF_6的存在提高了过渡金属Rh(PPh_3)_3Cl,Ru(PPh_3)_3Cl_2催化硅氢加成反应的活性,特别是β加成物的选择性。

Several early 14th-century theorists referred to the idea of an Ars Antiqua, represented primarily by Franco, and an Ars Nova instituted by Philippe de Vitry(see, for instance, CoussemakerS, iii, 371,408),but in historical terms the usefulness of the idea is supported more by the treatise Ars novae musicae(c1320)of Johannes de Muris, the 1324-5bull lf Pope John XXII decrying the musicians who were 'novellae scholae discipuli' and the reference in Jacobus of Liege's Speculum musice to 'moderni cantores' and to'aliquinunc novi'.
