14.5 ml (23.2 mmol) of n-BuLi (1.6 M in hexane) are added dropwise to a solution of 8 g (23.2 mmol) of 1,1′-dibromoferrocene in 30 ml of THF at a temperature of <−30° C. The mixture is stirred for another 30 minutes at this temperature. It is then cooled to −78° C. and 3.15 ml (23.2 mmol) of phenyldichlorophosphine are added dropwise at such a rate that the temperature does not exceed −60° C. After stirring at −78° C. for a further 10 minutes, the temperature is allowed to rise to room temperature and the mixture is stirred for another one hour. This gives a suspension of the monochlorophosphine X1.
