NUCLEAR MAGNETIC RESONANCE SPECTROSCOPY. STUDIES OF 1, 1, 4, 4-TETRAFLUORO-1, 3-ALKADIENES.

Abstract

1, 1, 4, 4-Tetrafluoro-1, 3-butadiene is indicated by dipole-moment studies to exist in the s-trans conformation. The F19-F19 spin-spin couplings constants for this compound are surprisingly similar to those of bis-4, 5(difluoromethylene)-cyclohexene and perfluoro-1, 2dimethylenecyclobutane both of which substances have their double bonds held in s-cis configurations. The results are related to the mechanism of transmission of fluorinefluorine spin-spin interactions and are inconsistent with a predominance of a 'through-space' mechansism of coupling. (Author)
