A model of silane decomposition in a radio-frequency argon plasma is constructed. The concentrations of SiH4 decomposition products, as well as products of synthesis (higher silanes), are calculated. The role of metastable argon atoms in the formation of SiH3 radicals and the higher silanes is analyzed. 相似文献

Summary For the primary alkyl halides (R=from C2H5 to n-C9H19; halogen=C1, Br, and I) and the simplest aryl halides (R=C6H5 and p-CH3C6H4) it was shown that the organomagnesium synthesis in absence of catalysts for the Grignard reaction can be applied with success to the preparation of heteroorganic compounds of elements of Groups II–IV (mercury, boron, aluminum, silicon, germanium, tin, phosphorus, arsenic, antimony). 相似文献

Heterocyclization of 2-chloroepoxy-1,1-diethoxy-2.3-butane with 2-amino-4-methylpyridine occurred with participation of all
three potential electrophilic centers to give 3,7-dimethyl-2-[N-(4-methylpyridyl-2)-4-hydroxy-3-methyl-5-oxopyrrolen-3-yl]imidazo[1,2-a]pyridine,
the structure of which was determined by X-ray crystallography.

The rate constants for Br(2P1/2) and Br(2P3/2) atoms in the reaction Br+CH3FHBr+CH2F in photobromination of CH3F have been determined. Their ratio is 10–(2.6±0.5) exp(10100±1000/RT) in the temperature range of 60–200 °C.

Summary Some dialkylphosphinic acids, dialkylphosphinous esters, and alkylenebis(dialkylphosphine) P,P'-dioxides were synthesized via organomagnesium compounds prepared in absence of ether and other catalysts for the Grignard reaction.This article is published in accordance with a resolution of the Conference of Chief Editors of Journals of the Academy of Sciences of the USSR of June 12, 1962, as a dissertation paper by B. N. Strunin. 相似文献

Results on determining the population of the A 3Σu electronic state of N2 molecules in a gas discharge using a relatively simple spectroscopic technique are reported. The technique proposed can be used not only in pure N2, but also in nitrogen-containing gas mixtures. The populations of the metastable and nonequilibrium B 3Πg states of nitrogen molecules are determined. It is shown that the electron-impact excitation is a dominant mechanism for populating the B 3Πg state. 相似文献
