Abstract: | Reactions of triaminophosphane (R2N)2P–NH2, (R = 1Pr) 1a, with aminodihalogenophosphanes 1Pr2N–PX2, 2a–c X = CL (a), Br (b), I(c)], in the presence of a base yielded the P-hydrogeno-iminophosphoranyl-halogenophosphanes (R2N)2PH = N–PX–N(1Pr)2 4a–c X = Cl (a), Br (b), I(c)]. Analogous reactions between 1a and 1b (b: R = c-hexyl) and chloroiminophosphane (Cl–P = N–Mes*, (Mes* = 2,4,6-tBu3C6H2) 6 , gave the P-hydrogeno(iminophosphoranyl)-σ2,λ3-iminophosphanes, (R2N)2PH = N–P = N–Mes* 8a and 8b. In solution 8a, 8b eliminated amine, yielding σ2, λ3-iminophosphanyl-substituted 1,3,2,4-diazadiphosphetidines (R2N)PN(P = N–Mes*)]2, 10a, 10b , and 11 ( 10a and 10b : cis; 11: trans). The X-ray structure analyses of compounds 4a, 4b, 8a, and 11 are discussed. © 1996 John Wiley & Sons, Inc. |
