Dimethylformamide → 3,4,5-Trifluorobenzoyl chloride

참여 물질

반응 단계

3,4,5-Trifluorobenzoic acid (0.176 g, 1.0 mmol) in dichloromethane (1.5 mL) was treated with a solution of oxalyl chloride (1.5 mL of 2 M in dichloromethane, 3 mmol) and a catalytic amount of N,N-dimethylformamide. The reaction was stirred overnight at ambient temperature. The excess oxalyl chloride was removed in vacuo to afford 3,4,5-trifluorobenzoyl chloride.
