A readily available pincer ruthenium(II) complex catalyzes the selective monoalkylation of (hetero)aromatic amines with a wide range of primary alcohols (including pyridine-, furan-, and thiophene-substituted alcohols) with high efficiency when used in low catalyst loadings (1 mol %). Tertiary amine formation via polyalkylation does not occur, making this ruthenium system an excellent catalyst for
当在低催化剂负载量下使用时,一种容易获得的pin式钌(II)配合物可以高效地催化(杂)芳族胺与多种伯醇(包括吡啶,呋喃和噻吩取代的醇)的选择性单烷基化。 1mol%)。不会发生通过聚烷基化形成叔胺的情况,从而使该钌体系成为合成仲胺的极佳催化剂。
