Homochiral BINAPDA-Zr-MOF for Heterogeneous Asymmetric Cyanosilylation of Aldehydes.

A new homochiral was prepared by a new chiral organic linker of ()-4,4'-(6,6'-dichloro-2,2'-diethoxyl-[1,1'-binaphthalene]-4,4'-diyl)dibenzoic acid () and ZrCl under solvothermal conditions. Its structure was determined by Pawley refinement on the basis of the measured PXRD pattern determined for , and it showed that the obtained chiral MOF crystallized in the 2 space group with the same topological structure as that of UiO-66. The obtained can be a very active catalyst to catalyze aldehyde cyanosilylation. In addition, the chiral was a typical solid catalyst, which was proved by a hot leaching test; moreover, it could be reused at least five times without loss of its catalytic activity and enantioselectivity.
