Fullerene C60 reacts with phosphine (PH3) under free radical initiation conditions (azobis(isobutyronitrile), xylene, 65°C, 6–11 h) to give in the presence of air oxygen functional oligofullerenes (yield up to 32%) containing functional groups of phosphinic and phosphonic acids. 相似文献

A practicable and environmentally benign process for the synthesis of Cobazole, an erythropoiesisstimulating agent, has been developed. The process is based on the reaction of N-vinylimidazole with cobalt chloride in water and requires no toxic organic solvents, which ensures the preparation of high-purity product. 相似文献

Addition of secondary phosphine oxides, phosphine sulfides and phosphine selenides to 3,7-dimethyl-2,6-octadienal (citral) (48–50°C, THF, argon) proceeds exclusively to the aldehyde group giving rise to new polyfunctional tertiary phosphine chalcogenides with diene and hydroxyl moieties in high preparative yield (up to 80%). 相似文献

Alkylthiochloroacetylenes react with sodium azide in mild conditions (20°C, DMSO) to give alkylthioethynyl azides and 4-chloro-5-alkylthio-4H-1,2,3-triazoles in a total yield of 72%. 相似文献

The lowest energy band in the photoelectron (PE) spectra of alkyl vinyl tellurides is attributed to-MO with predominant contribution from the pz-AO of the tellurium atom. The second and fourth lowest energy bands correspond to-MO. An additional-MO is located between these-MO. The introduction of a second vinyl group hardly affects the HOMO. The heterocyclization of divinyl telluride has a large perturbation effect. Nevertheless, divinyl telluride and tellurophene have the same type of orbital structure.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 4, pp. 935–939, April, 1991. 相似文献

The reveiw surveys and systematizes data on the role of defect formation in activation of red phosphorus. The reactivities of different modifications of elemental phosphorus (viz., white phosphorus, commercial red phosphorus, and red phosphorus containing high concentrations of biographical and induced defects) in inorganic and organic reactions were comparatively analyzed. 相似文献

Elemental phosphorus (red or white) reacts with 2-vinylnaphthalene while heating at 90-96°C in the superbasic KOH-DMSO system to form 2-(2-naphthyl)ethylphosphine, 2-(2-naphthyl)ethylphosphinic acid, bis[2-(2-naphthyl)ethyl]phosphine, bis[2-(2-naphthyl)ethyl]phosphine oxide, and tris[2-(2-naphthyl)ethyl]phosphine oxide in a total yield of up to 40%. Selective conditions for preparing the tertiary phosphine oxide from white phosphorus and 2-vinylnaphthalene in 58% yield were found. Phosphine and (2-phenylpropyl)phosphine add to 2-vinylnaphthalene in the KOH-DMSO system to form, under certain conditions, corresponding secondary phosphines in high yields. 相似文献
