Novel fluorine-containing carboxylic acid compounds of formula (II) are provided that can be reacted together with a base to produce industrially useful 3-(2-chloro-2-fluorovinyl)-2,2-dimethyl cyclopropanecarboxylic acid compounds of formula (I). The fluorine-containing containing carboxylic acid compounds of formula (II), if so desired, can be produced by reacting together a carboxylic acid compound of formula (III) and trichlorofluoromethane. In each of the formulas (I), (II), and (III), R is a lower alkyl group or a hydrogen atom. ##STR1##
提供了化学式(II)的新型含氟羧酸化合物,可以与碱反应,产生工业上有用的化学式(I)的3-(2-氯-2-氟乙烯基)-2,2-二甲基环丙烷羧酸化合物。如果需要,化学式(II)的含氟羧酸化合物可以通过将化学式(III)的羧酸化合物和三氯氟甲烷反应来制备。在化学式(I),(II)和(III)中,R是较低的烷基或氢原子。 ##STR1##
