Using zinc/hydrazine hydrate as a new reduction system, polyfluoroalkyl halides such as Cl(CF2)nH (1a-c, n = 4, 6, 8), Cl(CF2)nI (1e-g, n = 4, 6, 8) and R(CF2)nCl (n = 4, 6, 1h,i) have been converted to the corresponding reduction products H(CF2)nH (2a-g, n = 4, 6, 8) and R(CF2)nH (n = 4, 6, 2h,i) in high yield.Reduction of the CF2Cl group was faster than that of the CHI in the reaction of 1m. - Keywords: Polyhaloalkanes; Reduction; Zinc/hydrazine hydrate system; NMR spectroscopy; Mass spectrometry
