We report on heterogeneous dual photoredox-Lewis acid catalysis using a versatile and efficient nanocomposite: samarium oxide nanoparticle-decorated titanium dioxide. This emerging class of nanomaterials harnesses the Lewis acidity of the lanthanide, eliminates product contamination by the catalyst, and can be excited with visible light. Useful intermolecular and intramolecular net reductive and net neutral photoredox cyclization reactions are presented as examples of the general efficacy of this reusable heterogeneous nanocatalyst in synthetically relevant organic transformations.

使用单一双功能纳米材料的非均相双光催化氧化-路易斯酸催化

我们报告使用一种多功能和有效的纳米复合材料:氧化oxide纳米粒子修饰的二氧化钛异质双光氧化还原-路易斯酸催化。这种新兴的纳米材料利用了镧系元素的路易斯酸度,消除了催化剂对产物的污染,并且可以被可见光激发。提出了有用的分子间和分子内净还原和净中性光氧化还原环化反应,作为这种可重复使用的多相纳米催化剂在合成相关的有机转化中的一般功效的实例。
