  The preparation and characterization of the novel perhalogenated diazaphosphametalletidines, Cl3M[N(SiMe3)PCl2N(SiMe3)]·THF, M = Ti, Zr and Hf 2–4 and Cl4Nb[N(SiMe3)PCl2N(SiMe3)] 5 are reported. In addition, a new high yield preparation of the previously synthesized metallacycle Cl3Ti[N(SiMe3)PCl2N(SiMe3)] 1 is described. All reported complexes were synthesized by [3 + 1] cyclocondensation reactions involving the aminoiminophosphorane, (Me3Si)2NPCl2NSiMe3, and corresponding metal halides in dichloromethane. When 2.5 equivalents of (Me3Si)2NPCl2NSiMe3 were reacted with NbCl5 a complex series of products was identified by 31P1H} NMR spectroscopy; crystals of the unusual heterocycles [Cl3NbN(SiMe3)PCl2N}2Cl2NbN(SiMe3)PCl2N(SiMe3)}] 6 and [Cl2NbN(SiMe3)PCl2N(SiMe3)}]2-μ-Cl(NPCl2N) 7 were isolated. Complex 7 contains the first example of a ClNbNPNNb six-membered ring. Structural characterization by single-crystal X-ray diffraction is also reported for metallacycles 2, 3, and 5–7.

• Synthesis, Properties, and Bishomoaromaticity of the First Tetrahalogenated Derivative of a 1, 5-Diphosphadithiatetrazocine: A Combined Experimental and Computational Investigation

  The first example of a tetrahalogenated derivative of a diphosphadithiatetrazocine, 1,5-Cl2P(NSN)(2)PCl2 (3), was synthesized by cyclocondensation of a 2:1 mixture of SCl2 and SO2Cl2 with Cl2P(NSiMe3)N(SiMe3)(2) in CH2Cl2. The heterocycle 3 was isolated as an orange, moisture-sensitive, thermally labile solid and characterized by mass spectrometry, P-31 NMR, and UV visible spectroscopy, The low-field P-31 NMR chemical shift (93.7 ppm) is indicative of a cross-ring S-S interaction in the eight-membered P2N4S2 ring, and this conclusion is supported by densityfunctional computations. Compound 3 exhibits unusual physical properties compared with those of the known tetraalkyl or aryl derivatives; mild heating (90 degrees C) produces an orange rubbery material. The bishomoaromatic character of the diphosphadithiatetrazocine 1,5-R2P(NSN)(2)PR2 (R = Me, Cl, F) is evinced by the negative nucleusindependent chemical shift (NICS) values, and the through-space bishomoconjugation in the eight-membered ring decreases with increasing electronegativity of the substituents attached to the P atoms.
• Synthesis and Reactivity of Perhalogenated Acyclic and Metallacyclic Tantalum(V) Phosphoraniminato Complexes:  Discovery of an Unexpected Ligand Coupling Reaction To Form the Novel Phosphazenium Salt [N(PCl₂NH₂)₂][TaCl₆]

  The reaction of 1 with the aminophosphoranimine, (Me3Si)2NPCl2=NSiMe3, resulted in a [3 + 1] cyclocondensation reaction to form the metallacyclic complex, TaCl3(N=PCl3)[N(SiMe3)PCl2N(SiMe3)] (2), which contains a TaNPN four-membered ring and a phosphoraniminato ligand (N=PCl3). The analogous [3 + 1] cyclocondensation reaction between (Me3Si)2NPCl2=NSiMe3 and TaCl5 led to the isolation of TaCl4[N(SiMe3)PCl2N(SiMe3)]
