P-H functional transition-metal complexes were synthesized without using hazardous PH3 gas in good yields by photolysis of the transition-metal carbonyl complexes M(CO)(6-x) (M = Cr, W, Fe; x = 0, 1) in tetrahydrofuran followed by reaction with P2(SiMe3)4 and subsequent methanolysis to give the bridging complexes [(CO)(x)M(μ-PH2)]2 (M = Fe, x = 3 (1), M =(More)
Even in the context of hydrocarbons' general resistance to selective functionalization, methane's volatility and strong bonds pose a particular challenge. We report here that silver complexes bearing perfluorinated indazolylborate ligands catalyze the reaction of methane (CH(4)) with ethyl diazoacetate (N(2)CHCO(2)Et) to yield ethyl propionate(More)
Advanced (1)H, (13)C, and (31)P solution- and solid-state NMR studies combined with XPS were used to probe, at the molecular scale, the composition (of the core, the shell, and the interface) and the surface chemistry of InP/ZnS core/shell quantum dots prepared via a non-coordinating solvent strategy. The interface between the mismatched InP and ZnS phases(More)
Iron phosphides belong to a fascinating class of low-cost materials, exhibiting different properties depending on their phase (Fe3P, Fe2P, FeP, FeP2 and FeP4), and thus targeting a wide scope of applications (ferromagnetism, magnetoresistance, magneto-calorific effects, catalysis, and batteries). However, the synthesis of sizeand stoichiometry-controlled(More)
Materials: Cadmium acetate (Cd(OAc)2, ≥99.99%), HDA 98%, palmitic acid 99%, and tris(trimethylsilyl)phosphine ((TMS)3P, ≥98.0 %) were purchased from Strem. tris(N,N’diisopropylacetamidinato) Indium(III) was purchased from Nanomeps. Ethanol, toluene, mesitylene and pentane (RPE, Analysis grade) were purchased from Carlo Erba. All reagents and solvents were(More)
The synthesis and characterization (mainly by (19)F NMR and X-ray diffraction) of highly fluorinated aryl-4,5,6,7-tetrafluoroindazoles and their corresponding thallium hydrotris(indazolyl)borate complexes are reported [aryl = phenyl, pentafluorophenyl, 3,5-dimethylphenyl, 3,5-bis(trifluoromethyl)phenyl]. Thanks to N-H···N hydrogen bonds, the indazoles(More)
The control and understanding of the chemical and physical properties of quantum dots (QDs) demands detailed surface characterization. However, probing the immediate interface between the inorganic core and the ligands is still a major challenge. Here we show that using cross-polarization magic angle spinning (MAS) NMR, unprecedented information can be(More)
