Participants

Reaction Steps

To a solution initially at -35° C. of 3.609 g (20.7 mmol) of lithium (1-(trimethylsilyl)-2,4-dimethylpentadienide) in 30 mL of THF was added about 5 g (-46 mmol) of trimethylsilyl chloride. Copious precipitate formed immediately. After stirring overnight, the solvent was removed and the residue was extracted with pentane. After filtering, the solvent was removed under reduced pressure to give the product as a pale yellow liquid. The yield was 4.05 g, 81.3 percent. Major isomer: 1H NMR (C6D6) δ 5.72 (s, 1H), 5.50 (s, 1H), 1.88 (s, 3H), 1.85 (s, 2H), 1.69 (s, 3H), 0.20 (s, 9H), 0.06 (s, 9H). 13C NMR (C6D6) δ 151.8, 135.6, 128.9, 126.4, 27.8, 24.6, 23.5, 0.7, -0.2.
