An article Ipso-nitration of carboxylic acids using a mixture of nitronium tetrafluoroborate, base and 1-hexyl-3,4,5-trimethyl-1H-imidazolium tetrafluoroborate WOS:000474499200008 published article about PHOSPHONIUM IONIC LIQUIDS; AROMATIC-COMPOUNDS; SOLVOLYTIC BEHAVIOR; SELECTIVE NITRATION; ARYLBORONIC ACIDS; HIGHLY EFFICIENT; SULFONIC-ACID; METAL; CHEMISTRY; CATALYST in [Natarajan, Palani] Panjab Univ, Dept Chem, Chandigarh 160014, India; Panjab Univ, Ctr Adv Studies Chem, Chandigarh 160014, India in 2019.0, Cited 83.0. The Name is 4-Nitrobenzoic acid. Through research, I have a further understanding and discovery of 62-23-7. Safety of 4-Nitrobenzoic acid
An eco-friendly and a simple ipso-nitration protocol for a series of aliphatic and (hetero)aromatic carboxylic acids using nitronium tetrafluoroborate, 1-hexyl-3,4,5-trimethyl-1H-imidazolium tetrafluoroborate and base is reported. While contrasted with recently known decarboxylative ipso-nitration strategies for the preparation of nitro compounds, this protocol does not require a toxic metal catalyst and harmful volatile organic solvents. Moreover, this method is perfect for a broad range of functional groups and affords exclusively the ipso-nitrated product in moderate to good yields. (C) 2019 Elsevier Ltd. All rights reserved.
