A. Pelter et al., PREPARATION AND DIRECT OBSERVATION BY F-19 NMR-SPECTROSCOPY OF 1-FLUORO-1-LITHIOALKENES, Journal of the Chemical Society. Perkin transactions. I, (21), 1995, pp. 2681-2682
Two 2,2-diaryl substituted 1-fluoro-1-lithioalkenes (fluorine stabilis
ed alkenyl carbanions) have been synthesised and their half lives esti
mated by F-19 NMR spectroscopy.
