- چکیده:
- چکیده انگلیسی: Pyridinium based ionic liquids derived from β-picoline and n-alkylbromides were synthesized by a simple procedure at ambient temperature and then characterized. These neutral ionic liquids were investigated for their dual role as the solvent and promoter for the selective synthesis of a series of N-monomethylanilines using dimethylcarbonate as the methylating agent. A solvent free green procedure was developed. Reaction conditions were mild and the product recovery was simple. Excellent selectivity for N-monomethylation, the high yield of the product and recyclability of the ionic liquids are some of the promising features of this protocol.

- چکیده:
- چکیده انگلیسی: A mixture of two ionic liquids have been used for a green synthesis of 3,4,6-triarylpyridazine in high yield and at room temperature. The two ionic liquids acts in tandem. The advantage of this method is a room temperature synthesis of the target compounds using green methodology. Product recovery is simple and the mixture of ionic liquids can be recovered and recycled.
