The goal of this study is to evaluate a reaction mechanism which leads to the formation of a closo-carborane starting from B4H10 + C2H2. Experimentally, it is known that alkylboranes, nido-carboranes, and closo-carboranes can all be obtained depending on reaction conditions. For this study,...
;CONSTITUTION: A compound wherein (S) is 1 among the objective compounds of formula II ((s) is 0 or 1; μ and ω are each 0-3) can be obtained by reaction between an alcohol derivative of formula I (R1 is 3-20C alkyl or 3-20C alkoxyalkyl; A1...
This invention relates to the production of acetylene by incomplete combustion of hydrocarbons or gases containing the same. It is already known that acetylene can be obtained by the incomplete combustion of slightly unsaturated or satur... S Hans - US 被引量: 13发表: 1940年 Optimizing Flexural...
The intermediate van der Waals complex has also been observed by microwave spectroscopy 〈91JA2412〉. In the 1,2,3-trithiole series, 1,2,3-trithiole 2-oxide (29) was obtained in 39% yield from the reaction of 2,2-dimethyl-1,3,2-dithiagermole (112) with thionyl chloride (...
If moisture is present, the reaction between sodium hydride and acetylene is vigorous even at -60 deg C... Solid acetylene in admixture with liquid nitrogen at -181 deg C is sensitized by presence fo grit (carborundum) and may readily explode on impact ... Explosions in acetylene generators...
Ring annulations can be effectively carried out using a reaction of this type. As one of the unsaturated groups attached to the triple bond is usually also involved in the reaction, six-membered rings result. Reaction of 3-aminobenzisoxazole (350) with methyl propiolate gave ...
Electrocatalytic acetylene semihydrogenation is a promising alternative to thermocatalytic acetylene hydrogenation due to its environmental benignity and economic efficiency, but its performance is far below that of the thermocatalytic reaction because of strong competition from side reactions, including hydro...
Aromaticity can be assigned by Hückel’s rule, which predicts that planar rings with delocalized (4n + 2) π-electrons are aromatic, whereas those with 4n π-electrons are antiaromatic. However, for neutral rings, the maximal value of “n” to whi
An improved method is described for the preparation of certain acetylene-substituted polyimide oligomers which are substantially free of reaction solvent and thus do not fracture at use temperatures a
