No evidence for intramolecular hydrogen bonds in a-fluoro carboxamides
1997
Abstract
RMeCFCONH2 (R = H, cyclohexyl, Ph, 4-ClC6H4, 2-pyridyl) are prepd. by treatment of the corresponding a-hydroxy carboxamides with Et2NSF3. IR spectra argue strongly against the existence of intramol. H bonds between the NH2 group and the F atom. [on SciFinder (R)]
