Rational design of catalysts for asymmetric transformations is a longstanding challenge in the field of catalysis. In the current contribution we report a catalyst in which a hydrogen bond between the substrate and the catalyst plays a crucial role in determining the selectivity and the rate of the catalytic hydrogenation reaction, as is evident from a combination of experiments and DFT calculations
对于不对称转化的催化剂的合理设计是催化领域中的长期挑战。在当前的贡献中,我们报告了一种催化剂,其中底物和催化剂之间的氢键在决定催化氢化反应的选择性和速率方面起着至关重要的作用,这可以通过实验和DFT计算的结合来证明。详细的见解允许对催化剂进行计算机突变,使得仅该氢键相互作用更强,从而预测新催化剂更快。确实,我们通过实验证实,可以通过从配体上的尿素变为氧化膦氢键受体来增加这种相互作用的氢键强度,从而实现催化剂的优化。
