Zusammenfassung:PCT No. PCT/JP97/03037 Sec. 371 Date Apr. 27, 1998 Sec. 102(e) Date Apr. 27, 1998 PCT Filed Aug. 29, 1997 PCT Pub. No. WO98/08795 PCT Pub. Date Mar. 5, 1998A process for producing a fluorinated benzonitrile comprising hydrogenolyzing a fluorinated dicyanobenzene substituted with 1 to 4 fluorine atoms and having the remainder which may be substituted with a chlorine atom in the presence of a catalyst to cause hydrodecyanation of only the cyano group of one side and a process for producing a fluorinated benzyl alcohol comprising reducing the fluorinated benzonitrile and hydrolyzing the fluorinated benzonitrile and reducing the resultant corresponding fluorinated benzoic acid to convert the cyano group to a hydroxymethyl group.
