100 g (=0.513 mol) of phenylphosphonyl dichloride and 200 g (=1.45 mol) of phosphorus trichloride were mixed. This mixture was introduced dropwise, over the course of 3 hours, into a vertical quartz tube which was 60 cm long, filled with 6 mm diameter quartz Raschig rings, was flushed with nitrogen and was located in an electric oven heated to 600° C. The reaction mixture collecting in the trap was again introduced dropwise, over the course of 2 hours, into the quartz tube at 600° C. The reaction mixture now produced was distilled in vacuo. Apart from unreacted phosphorus trichloride and phosphorus oxychloride, 80 g of a distillate were obtained which, on the basis of a 31P NMR spectrum, had the following composition:
