These molecules are of interest across the wide spectrum of industrial and academic organic chemistry, so that organofluorine chemistry is economically highly important.Organofluorine Chemistry will help chemists to develop a systematic knowledge of the chemistry of fluorine with a view towards its application in the design of new reactions and syntheses, and the creation of novel fluorinated moOrganofluorine compoundsSynthesisHydrogen bondingLigands (Biochemistry)Organofluorine compoundsSynthesis.Hydrogen bonding.Ligands (Biochemistry)547.02547/.02Uneyama Kenji860648MiAaPQMiAaPQMiAaPQBOOK996205537903316Organofluorine chemistry1920507UNISA
