| Abstract: | An efficient method for the synthesis of fluoroaromatics with tetramethylammonium fluoride(TMAFanh.) as fluorination agent via the fluorodenitration reaction was reported. Fluoroaromatics were obtained from TMAFanh. and nitroaromatics by simply stirring them together at 80~100 ℃ for 1~5 h in an anhydrous solution of DMF in 19.4%~99.0% yields. The nucleophilic fluorinating method has the advantages of mild reaction conditions, high yields, easy work up and no phenol or ether side products were detected in the reaction. |
