A novel Ru(II) complex containing 4-(2-hydroxybenzyl)-3-methyl-5-oxo-2,5-dihydropyrazole-1-carbothioic acid methylamide has been applied as a catalyst for directly aminating alcohols. Preliminary investigation on the reaction mechanism has been done with the help of NMR spectroscopy recorded for regenerated catalysts and an NMR reaction. In addition, a plausible mechanism for the formation of the coupled
一种包含 4-(2-hydroxybenzyl)-3-methyl-5-oxo-2,5-dihydropyrazole-1-carbothioic acid methylamide 的新型 Ru(II) 络合物已被用作直接胺化醇的催化剂。借助再生催化剂和核磁共振反应记录的核磁共振波谱,对反应机理进行了初步研究。此外,还提出了一种可能的偶联产物形成机制。
