| titleOfInvention | Method for preparing formamide and N-methylamines through ligand-regulated selective reduction of carbon dioxide and amines |
| abstract | The invention relates to a method for preparing formamide and N-methylamines by ligand-controlled selective reduction of carbon dioxide and amines, wherein copper salt is used as a catalyst, organic amine or organic phosphine is used as a ligand, and CO 2 And hydrosilanes as C, respectively 1 Reacting a resource and a reducing agent, wherein amines are used as nucleophilic reagents in an organic solvent, the dosage of the catalyst is 1-5 mol%, the dosage of the ligand is 1-20 mol%, the reaction temperature is 20-80 ℃, and CO is 2 The pressure is 0.1-8.0MPa, the reaction time is 10-48h, the yield of formamide can reach 98% at most, and the yield of N-methylamine can reach 95% at most. The invention has the advantages that: the ligand is used as a regulation and control method for selective reduction preparation of formamide and N-methylamines for the first time; the catalyst is cheap and easy to obtain, and the composition is simple; widely-used, nontoxic, harmless and renewable CO 2 As raw materials, the use of traditional toxic formylation and methylation reagents is avoided; the substrate has wide application range and is suitable for various secondary amines. |
