Preparation of dichlorophenylphosphine via Friedel–Crafts reaction in ionic liquids
2003
Wang, Zhong-Wei | Wang, Lisheng
The Friedel–Crafts reaction of PCl₃ and benzene in [BuPy]Cl–XAlCl₃ ionic liquids (ILs) was investigated for clean synthesis of dichlorophenylphosphine (DCPP). A simple product isolation procedure was achieved, and the effect of ILs composition, reactant composition, reaction time and quantity of ILs on this reaction were studied. The [BuPy]Cl–XAlCl₃ rendered this reaction green characteristics. A catalytic mechanism was proposed as well.
