| titleOfInvention | Process for the preparation of dichlorophosphanes |
| abstract | In the process for the preparation of aryl dichlorophosphines of the general formula wherein R 1 , R 2 and R 3 are the same or different and represent a hydrogen atom, an alkyl group with 1-8 C atoms, a halogen atom, an aryl group or an aryloxy group, by reacting an arene of the general formula wherein R 1 , R 2 and R 3 have the above meaning, mjt at least 4 mol of phosphorus (III) chloride per mol of arene in the presence of aluminum chloride by boiling the mixture for several hours and subsequent precipitation of the aluminum chloride by adding a complexing agent, filtration and working up by distillation of the filtrate, 0.05 to 0.9 mol of aluminum chloride per mol of arene and 1-3 mol of finely ground alkali metal chloride are used as complexing agents per mol of aluminum chloride. |
