Asymmetric hydrogenation of 1-silyl-1-substituted alkenes has been explored, producing eight optically active silanes with good to excellent enantioselectivity (66–99% ee) and yield (74–99%). The reaction was efficiently catalyzed by the cationic N,P-Ir complexes, and the polar solvents were found to be essential for the stereocontrol of the conversion.
已经研究了1-甲硅烷基-1-取代的烯烃的不对称氢化反应,产生了八种具有良好至优异对映选择性(66-99%ee)和收率(74-99%)的光学活性硅烷。阳离子N,P -Ir络合物可有效催化该反应,并且发现极性溶剂对于转化的立体控制至关重要。
