Participants

Reaction Steps

Dry DMSO (20 mL) was added to 14 mmol of hexane-washed KH under Ar with stirring at RT. After H2 evolution ceased, a solution of tris-(p-chlorophenyl) methanol (3.63 g, 10 mmol) in 25 mL dry DMSO was added, giving a deep red anion solution. After 5 min,1-bromo-3-methyl-2-butene (2.0 mL, 19 mmol) was added and stirring continued for 1 h. The crude product was isolated by Et2O extraction and purified by flash chromatography (75 g SiO2, 5% EtOAc-hexanes) giving 3.93 g (91%) of (3-methyl-2-butenyl) tris-(4-chlorophenyl)methyl ether as an oil.
