Related Products of 3939-09-1, These common heterocyclic compound, 3939-09-1, name is 2,4-Difluorobenzonitrile, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: Aromatic or aliphatic nitriles (2 mmol) were dissolved in 5 ml of [bmim]HSO4 and the reaction mixture was heated at 60-65 C for 1-3 h. The progress of reaction was monitored by TLC. After completion of reaction, as checked by TLC, the reaction mixture was poured into water containing crushed ice. The product was precipitated out, filtered and dried. The yield of the final product was high (>90%) in all cases. All final products obtained were found sufficiently pure so it didn?t need further purification.The filtrate was concentrated under vacuum, washed with diethylether twice and concentrated under high vacuum. After proper drying under reduced pressure, approximately 95% ionic liquid was recovered from the reaction and compared with the original ionic liquid to check its authenticity. The efficiency of recovered ionic liquid in conversion of nitriles to acids was found unchanged in comparison to the original one and we reused it up to 5-6 cycles without any significant loss of its activity.
Statistics shows that 2,4-Difluorobenzonitrile is playing an increasingly important role. we look forward to future research findings about 3939-09-1.
