Steric hindrance by a metal–organic framework (MOF) is shown to influence the outcome of a catalytic reaction by controlling the orientation of its intermediates. This is demonstrated using an organocatalyst, phosphine MOF LSK‐3, which is evaluated with the aid of molecular modeling and NMR spectroscopy techniques. This report is the first application of phosphine MOFs in organocatalysis and explores
金属有机骨架(MOF)产生的位阻阻碍通过控制其中间体的方向影响催化反应的结果。使用有机催化剂膦MOF LSK-3可以证明这一点,该分子借助分子建模和NMR光谱技术进行了评估。该报告是膦MOF在有机催化中的首次应用,并探讨了构架空间位阻对催化反应施加选择性的潜力。这些发现扩大了非均相催化剂口袋中活性位点的控制和设计的机会。
