Benzene, 1-bromo-3,5-dimethyl- → 1,2-Bis(bis(3,5-dimethylphenyl)phosphino)benzene

참여 물질

반응 단계

3,5-Dimethylbromobenzene (5.54 g, 29.93 mmol) was added dropwise to magnesium (1.07 g, 44.03 mmol) and THF (30 mL) in an argon atmosphere. The reaction mixture was cooled to ambient temperature and filtered, and the thus-obtained THF solution of 3,5-dimethylphenylmagnesium bromide, and 1,2-bis(dichlorophosphino)benzene (0.95 g, 3.39 mmol) were reacted as in Production Example 1. The reaction was allowed to proceed overnight at 60° C. After purification, the title compound was obtained as a white powder (1.45 g, yield 76%).
