Cobalt-Catalyzed Asymmetric Hydrogenation of Vinylsilanes with a Phosphine-Pyridine-Oxazoline Ligand: Synthesis of Optically Active Organosilanes and Silacycles
The asymmetric hydrogenation of vinylsilanes catalyzed by a new C-1-symmetric phosphine-pyridine-oxazoline cobalt complex is described. The method provides an efficient approach to chiral tertiary silanes with enantioselectivities up to 99% ee. Furthermore, the o-methylsubstituted benzylic silane products undergo ruthenium-catalyzed dehydrogenative silylation to produce chiral benzosilolanes in high yields without racemization of the stereogenic center alpha to the quaternary Si atom.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 6224-63-1, you can contact me at any time and look forward to more communication. Computed Properties of C21H21P.
