1-chloro-2-dichlorophosphoryloxybenzene

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a reaction vessel there is added 113 g..phosphoryl chloride and 0.8 g. pyridine. Over a period of one hour, a total of 64 g. o-chlorophenol is added and the pot temperature is raised from 100° to 110°C. and held at 110°C. for one hour and then allowed to gradually cool to room temperature. The reaction mixture is stripped and there is obtained 108 g. product which affords, on distillation, 93.7 percent o-chlorophenyl phosphorodichloridate and 7.3 percent di-o-chlorophenyl phosphorochloridate. To a reaction vessel there is added 113 g the pot temperature is raised from 100° to 110°C. held at 110°C. for one hour there is obtained 108 g
