A Pt−Ni alloy nanocatalyst is developed for the diastereoselective directed hydrogenation of tetrasubstituted olefins in a cyclopentene scaffold. For this substrate class, established homogeneous catalysts generate hydrogenolysis side products, and commercial heterogeneous catalysts are not stereoselective. Uniform alloying of the noble metal and base metal combined with high catalyst dispersion is
开发了一种 Pt-Ni 合金纳米催化剂,用于环戊烯支架中四取代烯烃的非对映选择性定向氢化。对于此类底物,已建立的均相催化剂会产生氢解副产物,而商业多相催化剂不具有立体选择性。贵金属和贱金属的均匀合金化与高催化剂分散相结合对于一系列空间位阻烯烃的良好反应性和非对映选择性至关重要。
