cocrystallizing achiral (2,2,6,6-tetramethylpiperidin-1-yl)oxyl (TEMPO)-substituted tricarboxylate and enantiopure VO(salen)-derived dipyridine ligands. The chiral MOF can function as an efficient heterogeneous catalyst for the sequential alcohol oxidation/asymmetric cyanation of aldehyde reactions with enhanced activity and enantioselectivity compared to the homogeneous counterpart.
通过将非手性(2,2,6,6-四甲基哌啶-1-基)氧基(TEMPO)取代的三羧酸盐和对映体纯的VO(salen)衍生共结晶,成功地构建了带有自由基的手性多孔金属-有机骨架(MOF)。二吡啶配体。与均相对应物相比,手性MOF可以作为醛反应的顺序醇氧化/不对称氰化的有效多相催化剂,具有增强的活性和对映选择性。
