PROCEDURE

实验过程

A mixture of 2.63 g of 4-(bromomethyl)-4'-(trans-4-pentylcyclohexyl)biphenyl and 2.2 g of triphenylphosphine in 150 ml of o-xylene was heated to reflux (bath temperature 160° C.) for 15 hours in a sulphonation flask while gassing with argon. After cooling, the white precipitate formed was filtered off, washed several times with benzene and dried in a high vacuum (0.1 mmHg) at 80° C. for 1 hour. There were obtained 3.48 g (80%) of [[4'-(trans-4-pentylcyclohexyl)-4-biphenylyl]methyl]triphenylphosphonium bromide as a white powder (m.p. 263°-265° C.) which was used in the following Wittig reaction without further purification.
