Paragraph 0022-0027, (2021/05/08)
The invention provides a method for synthesizing an organic aromatic nitrogen-containing compound by taking nitrogen as a nitrogen source, and belongs to the field of organic synthesis. The invention provides a method for synthesizing an organic aromatic nitrogen-containing compound by taking nitrogen as a nitrogen source, which is characterized by comprising the following steps of: 1, reducing nitrogen by lithium powder to form lithium nitride; and 2, reacting the lithium nitride with a halogenated aromatic compound under the action of a transition metal catalyst, a ligand, alkali and a phase transfer catalyst to obtain an organic aromatic nitrogen-containing compound; wherein the two steps of reactions are completed in one pot. The method realizes the conversion of cheap nitrogen to the high-added-value aromatic nitrogen-containing compound, and also has the advantages of mild reaction conditions, good compatibility of substrate functional groups, high yield and the like.
One-pot synthesis of symmetrical and asymmetrical diphenylamines from guanidines with aryl iodide using Cu/Cu2O nanocatalyst

, (2020/06/01)
This work reports the selective one-pot synthesis of symmetrical and asymmetrical amines from guanidines as ammonia surrogate. The use of guanidine as ammonia source will eliminate the need of handling liquid ammonia. The reaction was performed using Cu/Cu2O nanocatalyst under ligand-free condition. The synthesized catalyst was characterized by a various technique like XRD, FEG-SEM, HRTEM and XPS. The different diphenylamines are produced in good to very good yields. Recyclability study of catalyst shows that up to five cycles there is no significant loss in its activity.
