Reaction Steps

130 ml (0.13 mols) of a THF solution of 1M of 4-pentenylmagnesium bromide was dropped in a solution of 200 ml of THF and 14.0 g of zinc chloride to obtain an organozinc reagent. The resultant mixture was added to a solution of 41.0 g (0.1 mol) of 1-chloro-4-(4-(trans-4-(4-cyanophenyl)cyclohexyl)butyl)-1-silacyclohexane in 300 ml of THF. The resultant product was found to be a mixture of trans and cis isomers with respect to the silacyclohexane ring. The product was subjected to ordinary aftertreatments, followed by isolation through chromatography to obtain 40.8 g (yield: 95%) of the intended trans isomer product.
