Method of asymmetrically hydrosilylating substrates using catalysts having a ligand of the compound of the formula (I)
wherein
R is optionally substituted alkyl, cycloalkyl, aryl or heteroaryl;
R′ is hydrogen, optionally substituted lower alkyl; and
R″ is hydrogen, halogen, optionally substituted alkyl, hydroxy, amino (e.g., primary, secondary or tertiary), alkenyl;
or an enantiomer thereof; or an enantiomeric mixture thereof with a transition metal. Particularly suitable reactions include the asymmetric hydrosilylation of ketones.
使用具有化合物公式(I)的配体的催化剂不对称地对底物进行氢硅烷化的方法
其中
R是可选择地取代的烷基、环烷基、芳基或杂环芳基;
R′是氢、可选择地取代的较低烷基; 和
R″是氢、卤素、可选择地取代的烷基、羟基、氨基(例如,一级、二级或三级)、烯基;
或其对映体; 或其与过渡金属的对映混合物。特别适合的反应包括酮的不对称氢硅烷化。
