ABSTRACT N-[2-P(i-Pr)(2)-4-methylphenyl](2)(-) (PNP) pincer complexes of tin(IV) and tin(II), [(PNP)SnCl(3)] (2) and [(PNP)SnN(SiMe(3))(2)] (3), respectively, were prepared and characterized by X-ray diffraction, solution and solid state NMR spectroscopy, and (119)Sn Mössbauer spectroscopy. Furthermore, (119)Sn cross polarization magic angle spinning NMR spectroscopic data of [Sn(NMe(2))(2)](2) are reported. Compound 2 is surprisingly stable toward air, but attempts to substitute chloride ligands caused decomposition.

    ABSTRACT: This review aims to develop an understanding of reactivity trends of p-block metal bases M(NR2)n (M = Sn: n = 2; M = Al, Ga, As, Sb: n = 3) towards organic substrates EHy containing one or more E-H bonds (E = B, N, P, S). These compounds not only act as good bases for the deprotonation of E-H bonds but recent advances in p-block amido chemistry have shown that, in addition, they can effect the dehydrogenic homo-coupling of primary phosphines and amines to give E-E bonded products. They have also been found to be active in stoichiometric and catalytic dehydrocoupling of amine-boranes, which has direct applications in hydrogen storage devices, revealing that these p-block catalysts offer potential alternatives to the extensive range of expensive and often highly toxic heavy metal catalysts. This perspective analyses three distinct reactivity patterns of p-block metal bases; deprotonation, stoichiometric dehydrocoupling and catalytic dehydrocoupling and attempts to rationalise reactivity in relation to the redox stability of the p-block metal.

    ABSTRACT: The reactivity of the chlorostannylene [HC(PPh2=NSiMe3)2SnCl] (2) with various substrates has been investigated. Compound 2 acts as a two-electron carbene-like ligand and forms a complex with W(CO)5THF (THF = tetrahydrofuran) to give [HC(PPh2=NSiMe3)2(Cl)SnW(CO)5] (4). It reacts with benzil and 3,5-di-tert-butyl-o-benzoquinone to give the oxidative cycloaddition products [HC(PPh2=NSiMe3)2(Cl)Sn{O(Ph)C=C(Ph)O}] (5) and [HC(PPh2=NSiMe3)2(Cl)Sn{O(3,5-di-tBu-C6H2)O}] (6), respectively. The metathesis reaction of 2 with excess sodium azide affords [HC(PPh2=NSiMe3)2SnN3] (7). With silver(I) triflate, it forms an ionic triflate salt [HC(PPh2=NSiMe3)2Sn][CF3O2SO] (8), which features an exceptionally long Sn···OSO3CF3 distance. It can act as a ligand-transfer reagent by reacting with [Fe{N(SiMe3)2}2] to give [HC(PPh2=NSiMe3)2Fe(μ-Cl)]2 (9). The X-ray structures of 2–9 have been determined.
