非常需要开发用于有机反应的有效的多相光催化剂。在这里,我们展示了一种新型的TiO 2(P25)负载的Cu和Mo光催化剂(Cu–Mo / TiO 2)的制备和催化性能,该光催化剂在室温下UV辐射下用醇对胺进行N烷基化。在不添加任何助催化剂(例如碱和有机配体)的情况下,将各种芳香族和脂肪族胺以中等至极好的收率选择性地转化为相应的仲胺或叔胺。值得注意的是,该催化体系在含卤素取代基的苯胺与醇的烷基化中是可行的,所需产物的产率高达95%。
The first examples of titanium-catalyzed hydroaminoalkylation reactions of ethylene with secondary amines are presented. The reactions can be achieved with various titanium catalysts and they do not require the use of high pressure equipment. In addition, the first solid-state structure of a titanapyrrolidine that is formed by insertion of an alkene into the Ti-C bond of a titanaaziridine is reported
