Preparation of fluorinated 1,2- and .alpha.,.omega.-diols
摘要:
The addition of perfluoroalkyl iodides to 7-octene-1,2-diol or 5-hexene-1,2-diol in the presence of Pd(Ph3P)4 or benzoyl peroxide gives the corresponding adducts in 71-88% yields. The adducts have been successfully reduced by hydrogenation using palladium on activated carbon as a catalyst to afford the fluorinated 1,2-diols R(f)(CH2)nCH(OH)CH2OH (n = 4, 6) in good yields. The fluorinated alpha,omega-diol HO(CH2)3CH(CH2C6F13)(CH2)3OH has been prepared by Pd(Ph3P)4-catalyzed addition of C6F13I to the diester (EtO2CCH2CH2)2C=CH2 followed by LiAlH4 reduction.
