研究了稀土金属有机化合物和第三族金属有机化合物催化单取代烯烃硅氢加成反应的区域选择性与催化剂结构的关系。各种各样的催化剂变化被证明与氢化硅烷化过程相容。合成了几种新型配合物，以拓宽本研究的范围。结果表明，含有较大的镧系金属离子和减少的取代基上的双金属配体的配合物产生增加的产率的仲硅烷产品。几种复合物被鉴定为高度选择性的伯硅烷生成。
The regioselectivity of monosubstituted alkene hydrosilylation catalyzed by organolanthanide and group 3 organometallic complexes has been studied as a function of catalyst structure. A wide variety of catalyst variations were shown to be compatible with the hydrosilylation process. Several novel complexes were synthesized to widen the scope of this investigation. The results show complexes containing larger lanthanide metal ions and reduced substitution on the cyclopentadienyl ligands produce increased yields of the secondary silane product. Several complexes were identified that are highly selective for primary silane generation.
