Magnesium → HCID 178495608, compound

Participants

Reaction Steps

35.5 g (100 mmol) of 4-(2-(trans-(4-(3-methoxypropyl)-4-silacyclohexyl))ethyl)phenyl bromide was dripped into a mixture of 2.4 g of magnesium (100 mmol) and 60 ml of THF to obtain a Grignard's reagent. This solution was then dripped into a 300 ml THF solution of 34.5 g of 4-chloro-3',4'-difluorobiphenyl and a catalytic amount of bis (1,3-diphenylphosphinopropane) nickel (II) chloride. After a conventional after treatment, the reaction mixture thus obtained was purified by means of chromatography to obtain 36.3 g (yield 81%) of the target product.
