Bis(2-phenylethyl)phosphine selenide was obtained with 86% yield from bis(2-phenylethyl)phosphine and selenium. XRD, IR, UV, and multinuclear NMR spectroscopic studies revealed that the phosphorus atom in the bis(2-phenylethyl)phosphine selenide molecule is four-coordinated irrespective of the phase state (crystals or solution). 相似文献

Structures of 2-(diorganylphosphorylhydroxymethyl)-1-organylimidazoles were studied by IR and 1H and 3
1P NMR spectroscopy, and also by ab initio calculations (HF/6-31G*). Formation of intramolecular O-H+++O = P hydrogen bonds in solutions of these compounds in CCl4 and CHCl3 was established. 相似文献

Nucleophilic addition of secondary phosphine sulfides to an aldehyde of the azole series occurs under noncatalytic conditions in THF at room temperature and enables the preparation in high yield of imidazoles and benzimidazoles with thiophosphoryl and hydroxyl groups, which are promising building blocks for organic synthesis and polydentate ligands for metal complexes.Dedicated to Academician V. I. Minkin on his 70th birthday.__________Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 3, pp. 365–371, March, 2005. 相似文献

The paper gives the results obtained in a study of the structure of coumarin derivatives by the following metheds: ozonization of the double bonds in the monomeric and polymeric coumarins, and also in mixtures of polyvinylpyrrolidone with monomeric coumarins, and the treatment of the monomeric coumarins under the conditions of radical copolymerization but without the participation of N-vinylpyrrolidone.Institute of High-Molecular-Weight Compounds, Academy of Sciences of the USSR, Leningrad.

Alkyldibenzyl- and benzyldialkylphosphine oxides were prepared in one stage by direct phosphorylation of a mixture of alkyl bromides and benzyl chloride with red phosphorus under the conditions of phase-transfer catalysis (concentrated aqueous KOH solution-dioxane-benzyltriethylammonium chloride). 相似文献

The phosphorylation of 2-vinyl- and 4-vinylpyridines by white phosphorus and active modifications of red phosphorus (obtained by thermal polymerization of white phosphorus in the presence of graphite or the action of ionizing radiation in benzene) in the KOH/DMSO superbase system at room temperature leads to the formation of tris[2-(2-pyridyl)ethyl]- and tris[2-(4-pyridyl)ethyl]phosphine oxides in 58-72% yield. These oxides are promising ligands for design of metal complex catalysts. These vinylpyridines react less efficiently with ordinary red phosphorus and the yield of the corresponding tris(2-pyridylethyl)phosphine oxides does not exceed 10%. 相似文献
