A Route to Novel Functionalized Bis(imino)phosphoranes XP(NAryl)NAlkyl Chloro(arylimino)phosphane ( 1 ) reacts with alkyl azides RN 3 (R t Bu, Et 3 C, 1‐Ad) to form 4,5‐dihydro‐1 H ‐tetrazaphos‐pholes 2a‐c . The thermal decomposition of these compounds results in the formation of the diazadiphosphetidines 4a–c via the chlorobis(imino)phosphorane intermediates 3a–c , which were detected by NMR spectroscopy. By treating 2a with the lithium salts Li( n Bu, C 5 Me 5 , NHAryl, OAryl, t BuS) the 4,5‐dihydro‐1 H ‐tetrazaphosphole intermediates 5a–d are obtained, which by elimination of nitrogen form the bis(imino)phosphoranes 6a–e . The X‐ray structure determination of the phosphane derivative t Bu 2 PP(NCEt 3 ) NAryl ( 7 ), obtained by the same procedure, is discussed.
