The preparation and coordination chemistry of iPr2P(E)NHP(E′)iPr2 (E, E′=Se; E=Se, E′=S; E=S, E′=O; E,E′=O

Deposition of II‐VI Thin Films by LP‐MOCVD Using Novel Single‐Source Precursors

“…[18,19] The synthesis of the precursor involves deprotonation of the NϪH moiety, using sodium methoxide, to form anionic chelate complexes which is subsequently reacted with the metal chloride (Scheme 1). These reactions have some advantages over the routes via metal carbonates and higher yields are obtained particularly for the selenium complexes.…”

Aerosol-assisted CVD of cadmium diselenoimidodiphosphinate and formation of a new iPr2N2P3+ ion supported by combined DFT and mass spectrometric studies

“…The pyrolysis transfer line and injector temperatures were set at 350 °C, the heated interface at 280 °C, the EI source at 230 °C and the MS quadrupole at 150 °C. The carrier gas (helium) pressure was kept at 14 psi with flow rate of 1 cm 3 min -1 and the samples were introduced in split mode (split ratio 50:1 30 The imidodiselenodiphosphinato ligand (4.55 g, 11.18 mmol) was dissolved in dry MeOH, stirred for 30 minutes and NaOMe (0.60 g, 11.18 mmol) added. A brown colouration was observed, followed by gentle heating which became progressively darker and transparent.…”

“…Good precursors for example, dithio-or diseleno-carbamates must meet a number of requirements including: high purity, exclusion of extrinsic impurities that can act as dopants and clean decomposition on the substrate surface. 3 The dichalcogenido imidodiphosphinate ligands, [(EPR2) 2N] − (E = S, Se, Te) considered as inorganic analogues of acetyacetonates display rich coordination behaviour towards main group and transition metal ions [4][5][6][7][8][9][10][11] . Thin films have been prepared from these at reduced or atmospheric pressure involving delivery at low pressure, from an aerosol or by entrainment [12][13][14] .…”

New tellurium-containing ring systems

“…1) [9,10]. This approach is not effective for the synthesis of ditelluro PNP ligands because the direct reaction of the phenyl-substituted derivative PPh2N(H)PPh2 with tellurium does not result in significant oxidation even after prolonged periods in boiling toluene [8].…”
