lanthanide catalysts showed high catalytic activity and a wide scope of substrates with good to excellent yields under solvent‐free conditions. Efficient activation of the transamidation can be realized by the above complexes acting as cooperative acid–base bifunctional catalysts, which are proposed to be responsible for the higher reactivity in comparison with simple monometallic catalysts.
已经开发出一种实用的杂双金属镧系元素催化的伯,仲和叔酰胺与脂肪族和芳香族胺的酰胺化反应。该方法还应用于弱反应性硫代酰胺,以证明其多功能性和广泛的底物范围。杂双金属镧系元素催化剂在无溶剂条件下显示出高催化活性和多种底物,收率良好至优异。可以通过上述配合物作为酸基双官能催化剂,来实现转酰胺基的有效活化,与简单的单金属催化剂相比,这些络合物被认为具有更高的反应活性。
