biphenylene-bridged siloxane precursor in the presence of surfactant templates to give periodic mesoporous organosilicas (PMOs) functionalized with BINAP. Complexation of ruthenium followed by asymmetric catalytic hydrogenation and asymmetric transfer hydrogenation were carried out, and demonstrated that high levels of activity and selectivity are achievable with the chiral material.
制备了新颖的双三乙氧基甲硅烷基-BINAP单体,并在表面活性剂模板的存在下与联苯桥连的硅氧烷前体共缩合,得到了周期性的介孔有机硅(PMO),其被BINAP官能化。进行钌的络合,然后进行不对称的催化氢化和不对称的转移氢化,证明使用手性材料可以实现高水平的活性和选择性。
