4-Bromo-1,2-difluorobenzene → HCID 178495610, compound

Participants

Reaction Steps

19.3 g (0.1 mol) of 1-bromo-3,4-difluorobenzene was dripped into a mixture of 2.5 g (0.11 mol) of magnesium and 300 ml of THF to obtain a Grignard's reagent. This solution was then dripped into a 500 ml THF solution of 0.5 g of tetrakis triphenylphosphine palladium and 43.8 g (0.1 mol) of 4-(trans-4-(2-(trans-4-(3-methoxypropyl)-4-silacyclohexyl)ethyl)cyclohexyl)phenyl bromide. After a conventional after treatment, purification was conducted by means of chromatography to obtain 28.9 g (yield 61.3%) of 4-(trans-4-(2-(trans-4-(3-methoxypropyl)-4-silacyclohexyl)ethyl)cyclohexyl)-3',4'-difluorobiphenyl was obtained.
