실험 절차

A mixture of 375.9 g (1.67 mol) of 3-bromotetrafluoropropionic acid, 10 g of ferric chloride, and 488.7 g (2.50 mol) of benzotrichloride was refluxed for 1.5 h, then crude product was removed, bp about 60°. Redistillation gave 287.9 g (71%) of 3-bromotetrafluoropropionyl chloride, bp 67°-68°. IR (CCl4): 5.53 (C=O). ##STR44##
