for the direct N‐alkylation of amines with molecular hydrogen for the first time. A broad range of interesting and industrially relevant secondary and tertiary amines are obtained in the presence of an in situ formed Ru/Triphos complex. Notably, plant oil can be efficiently applied in this single‐step process. Moreover, a variety of other methyl esters can be used as N‐alkylation agents in the presence
甘油三酸酯首次用于胺与分子氢的直接N-烷基化。在原位形成的Ru / Triphos配合物的存在下,可获得广泛的有趣且与工业相关的仲胺和叔胺。值得注意的是,植物油可以有效地应用于此单步过程中。此外,在氢存在下,各种其他甲酯也可用作N-烷基化剂,用于合成更高级的结构单元。
