A base- and metal-free three-component reaction of ynones, sodium azide, and alkyl halides is developed for the ?regioselective synthesis of 2,4,5-trisubstituted-1,2,3-triazoles. The method is general, convenient, environmentally benign, atom-?economical, and high-yielding. 被引量: 10 年份...
更新1: what is the equation of reaction?I don't know how to write it.Moreover I remember chlorine is alkaline why you say it is acidic?Is there any reaction beeen base and non-metal oxide? If so is it neutralization? Firstly consider the non-metal oxide. A non-...
ester - formed by reaction between an acid and an alcohol with elimination of water muton - the smallest unit of DNA where a mutation can occur U, uracil - a base containing nitrogen that is found in RNA (but not in DNA) and derived from pyrimidine; pairs with adenine ...
state and, therefore, the heat of oxidation reaction thereof efficiently progresses the melting of the base metal 4. Since the carbon in the base metal 4 is successively burned in the oxidation process of the base metal in the high-temp. state and, therefore, the base metal which melts and...
of the base metal to be oxidized by the ferric ion species, thereby causing the ferric ion species to be converted to a ferrous ion species, and oxidizing the ferrous ion species with an oxidation mixture of SOand oxygen to form the ferric ion species for subsequent reaction with the ...

Dichromate ion reacts with chlorate ion in fused NaNO3-KNO3 mixtures to form chlorine and oxygen. Chloride is found to catalyze the reaction. The postulated mechanism includes Cr2O72- + ClO3- K ClO2+ + 2CrO42- (rapid equilibrium) ClO2+ ... Schlegel,James - 《Journal of Physical Chemistr...
Base metals are used in jewelry and industry. Here is the explanation of what a base metal is, along with several examples.
