Reaction Steps

19.87 g (25.8 mmol) of 2,2'-bis(phenyl-4-dimethylaminophenyl-phosphinylmethyl)-1,1'-binaphthyl and 15.5 ml (66 mmol) of tributylamine are initially charged in 80 ml of degassed, dry o-xylene in an argon atmosphere while stirring and 9.4 ml (65 mmol) of phenyldichlorosilane are added dropwise. The mixture is subsequently heated at 145° C. for 7 hours while stirring. The reaction mixture is cooled, admixed with 50 ml of degassed 32% strength sodium hydroxide solution and the phases are separated. The organic phase is concentrated and the solid formed is filtered off and recrystallized from acetonitrile. This gives 14.3 g of colorless crystals, corresponding to a yield of 75%.
