  Reaction of HN(PiPr2)2 with one equivalent of selenium in hexane at room temperature yields the monoselenide as the P–H tautomer SePiPr2–NP(H)iPr2 (2b). Deprotonation of 2b with nbutyllithium in the presence of TMEDA at −78 °C followed by addition of tellurium produces the air-sensitive, mixed chalcogenido complex [(TMEDA)Li(SePiPr2)(TePiPr2)N] (8Li) in >97% purity after recrystallisation. Similarly, deprotonation of TePiPr2–NP(H)iPr2 (2c), followed by addition of sulfur, gives the sulfur analogue [(TMEDA)Li(SPiPr2)(TePiPr2)N] (7Li) in >99% purity. The symmetrical complexes [(TMEDA)Li(SePiPr2)2N] (4Li) and [(TMEDA)Li(TePiPr2)2N] (5Li) are produced by similar methods. Compounds 2b, 4Li, 5Li, 7Li and 8Li were characterised in solution by multinuclear (1H, 31P, 77Se and 125Te) NMR spectroscopy and their solid-state structures were determined by X-ray crystallography. The X-ray crystal structures of the polymeric chains [NaN(EPiPr2)2]∞ (4Na, E = Se and 5Na, E = Te) are also reported.

  The lithiation of the monotelluride TePPri2NP(H)Pri2 (2) with BunLi at −78 °C results in the formation of the reagent [LiTePPri2NPPri2] (5), which was characterized by 31P NMR spectroscopy but not isolated due to disproportionation upon solvent removal. Salt metathesis reactions of 5, generated in situ, with group 12 metal chlorides produce the complexes M(TePPri2NPPri2)2 (6, M = Zn; 7, M = Cd; 8, M = Hg), which were characterized by single crystal X-ray diffraction, multinuclear NMR spectroscopy and thermal analyses. The X-ray structures reveal distorted tetrahedral structures with two P,Te-chelating anionic ligands [TePPri2NPPri2]−. The 31P NMR spectra exhibit second order behaviour that arises from an AA′XX′ spin system; the spectra were simulated to determine the 31P, 31P spin–spin coupling constants.

  The reaction of two equivalents of (TMEDA)Li[(EPiPr2)(TePiPr2)N] (E = S, Se) with NiBr2(DME) in THF at 23 °C yields homoleptic complexes of heterodichalcogenido PNP ligands Ni[(EPiPr2)(TePiPr2)N]2 (2, E = S; 3, E = Se). Similarly, the complexes Ni[(PiPr2)(EPiPr2)N]2 (4, E = Se; 5, E =Te) are obtained by in situ deprotonation of the neutral monochalcogenides EPiPr2NP(H)iPr2 (E = Se, Te) with nBuLi in THF at −78 °C followed by addition of NiBr2(DME). The complexes 2–5 have been characterised by multinuclear (1H, 31P, 77Se and 125Te) NMR spectroscopy in solution and by X-ray crystallography in the solid state, the results of which show that they all exist as the square planar, trans isomers. Aerosol-assisted chemical vapour deposition (AACVD) of Ni[(SePiPr2)(TePiPr2)N]2 yields crystalline Ni0.51Te films at 450–500 °C, which were analysed by X-ray powder diffraction (XRPD), scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX) and X-ray photoelectron spectroscopy (XPS).

  of the type EPR2NP(I)R2 have been developed. The reaction of Li[EPiPr2NPiPr2] with one molar equivalent of I2 produces EPiPr2NP(I)iPr2 (3a-I, E = Se; 3b-I, E = Te). Alternatively, the oxidation of Na[N(PtBu2)2] with I2 in tetrahydrofuran (THF) generates the P(III)/P(V) compound tBu2PNP(I)tBu2 (6′-I) which, on treatment with elemental selenium or tellurium in THF, yields EPtBu2NP(I)tBu2 (3a′-I, E = Se;
