a range of para-substituted acetophenones XC6H4COCH3 (X = H, Me, MeO, F, Cl, NO2) with 1,1,3,3-tetramethyl disiloxane mediated by complexes of rhodium (I) and platinum (II) was investigated. The complexes of platinum (II) are less effective than complexes of rhodium (I), but display greater selectivity. Six 1-(1′-arylethoxy)-1,1,3,3-tetramethyl disiloxanes have been synthesized by hydrosilylation using
一系列对位取代苯乙酮 XC6H4COCH3(X = H、Me、MeO、F、Cl、NO2)与 1,1,3,3-四甲基二硅氧烷的氢化硅烷化反应,由铑 (I) 和铂 (II) 的络合物介导被调查。铂 (II) 的配合物不如铑 (I) 的配合物有效,但显示出更高的选择性。已经使用几种偶联催化剂通过氢化硅烷化合成了六种 1-(1'-芳基乙氧基)-1,1,3,3-四甲基二硅氧烷。
