Reaction of (NPCl2)2NSOCl or (NPCl2)2NSOF with benzene in the presence of AlCl3 yields (NPCl2)2NSOPh. By the same procedure two isomeric forms of NPCl2(NSOPh)2 can be obtained from cis-NPCl2(NSOCl)2. The phenylated products were characterized by IR, mass and 31P NMR spectra.Reactions of one of the isomers of NPCl2(NSOPh)2 with (CH3)2NH yield NPClN(CH3)2(NSOPh)2 (molar ratio 1:2) and NP[N(CH3)2]2(NSOPh)2 (molar ratio 1:6.8). The structures of the amino substituted derivatives were determined by means of 1H NMR measurements.

Friedel-Crafts reactions of (NPCI,)2NSOCl with a series of monosubstituted benzenes C,H,R (R = Me.OMe. Et, 'Pr, CI, Br and I) provide the sulfur substituted products (NPC12)2NSOGH,R in 40-9056 yield. When R = Me or OMe, ortho-and para-isomen are formed. With the other benzenes, only the puru substituted derivative is formed. From the reaction of cis-NPCl, (NSOCI), with chlorohenzene. five of the six possible isomers of NPCl,(NSOGH,Cl)2 have been isolated and characterized. Structure assignments are based on "P and !H NMR data and are confirmed by the X-ray structure data of the truns-orrho-puru isomer.

Durch Anwendung der Appel‐Reaktion (CCl4/PPh3 in NEt3/CH3CN) mit Triphenylphosphin im Überschuß gelingt die Überführung der Aminoliganden in Cylotriphosphazenen in die entsprechenden Triphenylphosphoranylidenaminoliganden.
