-pentylidene (2), using tetrakis(dimethylamino)ethene (TDAE), and these dienes are very reactive. With alkali metal fluorides, 4 gave a stable observable anion while 3 gave oligomers. The corresponding fluorinated allyl anion was however obtained via3 in the presence of TDAE. Further reactions of 3 and 4 are described.
