A process for producing a 2-fluorocyclopropane-carboxylic acid of formula \x9bI! ##STR1## by reducing a 2-halo-2-fluorocyclopropanecarboxylic acid of formula \x9bII! ##STR2## the reduction being carried out by developing a Raney nickel alloy in the presence of the 2-halo-2-fluorocyclo-propanecarboxylic acid of formula \x9bII!, or by contacting the 2-halo-2-fluorocyclopropanecarboxylic acid of formula \x9bII! with hydrogen in an aqueous solvent using a Raney nickel catalyst.
通过在存在2-卤代-2-氟环丙烷羧酸\x9bII!的情况下开发Raney镍合金或者使用Raney镍催化剂在水溶剂中将2-卤代-2-氟环丙烷羧酸\x9bII!与氢接触,进行还原,从而生产化学式为\x9bI!的2-氟环丙烷羧酸的方法。
