hydrogenation of ketones derived from acetophenone has been studied. The aim was observe the effect on activity and selectivity to aromatic alcohols by the presence of substituents in the ring. The chemical characteristics of substituents groups could influence the way aromatic ketones are absorbed on the metallic surface. This fact can be explained by a combination of geometric and electronic effects.
芳族酮的催化还原是导致获得醇的有趣反应。这些醇中的一些用作生产化学精细化合物的中间体。双金属催化剂广泛用于化学选择氢化中。金属表面有机金属化学(SOMC / M)是用于获得双金属系统的方法。 在本工作中,已经研究了衍生自苯乙酮的酮的氢化。目的是观察在环中存在取代基对芳族醇的活性和选择性的影响。取代基的化学特性可能影响芳族酮在金属表面上的吸收方式。这个事实可以通过几何效应和电子效应的组合来解释。
