Research on Phosphorus-Nitrogen-Polymers; Substitution-Rules on Trimeric Phosphonitrilic Chloride

摘要

The diphenyl derivative is easily obtained by the reaction of trimeric phosphonitrilic chloride with AlCl3 in benzene. The two phenylgroups are attached to the same P atom. This compound can be converted into a di- or tetramino compound by reaction with ammonia; the latter compound was obtained in two different modifications. The ammonia attacks first in the 3 and 5 positions, leading to a product in which the aminogroups are attached to different P atoms. Further attack on the disubstituted compound leads to tetrasubstituted diphenyl derivatives. Condensation of the amino compounds can be effected by splitting out ammonia. The NMR spectra confirms the postulated structures. (Author)
