Thus, we have shown how to degrade one pyrrolic unit of the starting material, [meso-tetraphetiylporphyrinato]Ni(II) (2) in three steps to an aldimine linkage. The conformational changes of the porphyrinic macrocycle during the course of this degradation, as determined by comparison of the X-ray crystal structures of the compounds, are discussed. A comparative study delineates the UV-Vis spectroscopical consequences. In addition, the chemical reactivity of [meso-tetraphenylchlorophinato]Ni(II) (6) suggests the existence of an azepine-derived pyrrole-modified porphyrins (11, 12). (c) 2004 Elsevier B.V.

The behaviour of 1 as a potential precursor in the generation of a dinitrogen coordination complex is described. Reduction of 1 with potassium-graphite (C8K), under dinitrogen, under a variety of conditions led to a number of products, one of which is the dinuclear derivative with bridging P-phenyl groups that has the general formula {[P2N2]Hf}(2) (2). Reduction of the hafnium diiodide [P2N2]HfI2 (3) - prepared via the reaction of 1 with excess Me3SiI - with C8K results in the formation of ([P2N2]Hf)(2)(mu-eta(2):eta(2)-N-2) (4) as the major product of the reaction, while {[P2N2]Hf}(2) (2) and [P2N2]Hf(C7H8) (5) appear to be minor products. Reaction of 1 with 2 equiv of MeMgCl gives [P2N2]HfMe2 (6), which, upon exposure to an atmosphere of H-2, gives the hafnium tetrahydride {[P2N2]Hf}(2)(m-H)(4) (7).},

The solution H-1- and P-31{H-1}-NMR spectra are consistent with a C-20 symmetric species in solution. The X-ray crystal structure shows the hydride to be monomeric, and free from interaction with either salt (LiCl) or external base (Et2O). The coordination of both phosphines of the macrocycle to the metal center is found in the solid state. Solution molecular weight measurements are consistent with a monomeric structure. The gallium hydride syn-GaH[P2N2] (5) is synthesized by the addition of LiGaH4 to syn-MCl[P2N2] (M = Ga (2), In (3)). This species is unstable and could only be characterized in solution. Reduction of syn-MCl[P2N2] (M = Ga (2), In (3)) with KC8 yields the reduced, dimeric species {syn-M[P2N2]}(2) (M = Ga (6), In (7)). The solution H-1- and P-31{H-1}-NMR spectra are consistent with C-2v symmetric species in solution. The X-ray crystal structures of the gallium and indium complexes confirm the presence of unsupported metal-metal bonds in both cases. The features of the solution H-1- and P-31{H-1}-NMR spectra suggest that both dimers are fluxional in solution. (C) 1999 Elsevier Science S.A. All rights reserved.},
