摘要
(Chemical Equation Presented) Doing the twist: Differences in behavior between isomers of straight-chain alkanes bearing four vicinal fluorine atoms are revealed by conformational analyses (X-ray diffraction, NMR spectroscopy). For example, computational studies show that the all-syn vicinal fluoroalkane (see picture, C gray, F green, H white) adopts a helical conformation, while the anti-synanti isomer prefers to be linear. © 2007 Wiley-VCH Verlag GmbH & Co.
