from stoichiometric waste products into catalysts and a new concept for catalytic phosphorus-based activation and nucleophilic substitution of alcohols has been validated. The present study has focused on a full exploration of the scope and limitations of phosphine oxide catalyzed chlorination reactions as well as the development of the analogous bromination reactions. Further mechanistic studies, including
已经开发了催化磷(V)介导的醇的氯化和溴化反应。新反应构成了经典Appel卤化反应的催化形式。在这些新反应中,草酰氯用作消耗化学计量试剂,以产生卤化catalytic盐,这些卤化salts盐由催化氧化膦。因此,氧化膦已经从化学计量的废物转化为催化剂,并且已经验证了基于催化磷的醇的活化和亲核取代的新概念。本研究集中于对氧化膦催化的氯化反应的范围和局限性的全面探索,以及类似溴化反应的发展。进一步的机理研究,包括对催化循环中间体的密度泛函理论计算,与以卤代和烷氧基phosph盐为中间体的催化循环是一致的。
