Participants

Reaction Steps

625 ml (1 mol) of 1.6 M BuLi are added dropwise at −78° C. to a solution of 114 g (1 ml) of 1,2-difluorobenzene in 11 of dry tetrahydrofuran. After 1 hour, 140 ml (120 g, 1.1 mol) of trimethylsilyl chloride are slowly added dropwise at −78° C. The mixture is allowed to warm to room temperature overnight, and then 200 ml of methyl ter-butyl ether and 200 ml of water are added. The organic phase is washed with water (2×100 ml) and sat. NaCl (1×100 ml) and dried using magnesium sulfate, and the solvent is removed under reduced pressure. 170 g (91%) of 5 distil over from the residue at from 100 to 102° C./70 mbar.
