Procedure
In this process, the reaction product of phenyldichlorophosphine and p-cyanophenyl-diazonium-tetrafluoroborate has to be subjected to a reduction with aluminum in order to obtain the p-cyanophenyl-phenylchlorophosphine. The yield is 47 % of the theoretical yield. This process can be carried out only with difficulty on a large scale, and the formation of large amounts of fluorine containing waste secondary products creates the problem of the pollution-free destruction thereof.
