The novel multicomponent reaction of [60]fullerene with dimethyl acetylenedicarboxylate and isoquinoline, quinoline or substituted quinolines was investigated. This type of reaction presents the first example of a 1,4-dipolar cycloaddition reaction in fullerene chemistry.

Reaction prediction remains one of the great challenges for organic chemistry. Solving this problem computationally requires the programming of a vast amount of knowledge and intuition of the rules of organic chemistry and the development of algorithms for their application. It is desirable to develop algorithms that, like humans, "learn" from being exposed to examples of the application of the...

This work described an efficient Pseudo four-component synthesis of (10E)-N-benzylidene-2-phenylH-imidazo[1,2-a]pyridin-3-amine derivatives from 2-aminopyridin, malononitrile and arylaldehydes in the presence of NaOH under solvent-free and conventional heating condition in good to excellent yields. A wide range of aromatic aldehydes would easily undergo condensations with 2-aminopyridin and mal...

A general mathematical description, mostly in terms of graph theory, is given for reactions of organic chemistry. The corresponding computer program generates all products that can result from a given set of starting materials interacting according to a given set of reaction schemes. Example reactions from combinatorial chemistry, synthetic organic chemistry, and mass spectroscopic structure el...

Radicals known to play significant roles in hydrogen peroxide chemistry include the hydroxyl radical (OH ), superoxide radical (O2 ), and perhydroxyl radical (HO2 ). Different radicals dominate the reaction under different chemistry conditions, and are controlled by parameters such as concentration of the oxidant, catalyst, organic or inorganic solutes, and pH. This can affect performance as so...

The discovery of novel chemical reactions or reaction sequences that are able to generate useful chemical products may be regarded as the heart of organic chemistry. We present here concepts and methods on how to find and explore new multi component reactions, especially with automated combinatorial methods. This "combinatorial reaction finding" provides also a powerful tool to the understandin...

Even if water is the natural environment for bioorganic reactions, its use in organic chemistry is often severely limited by the high insolubility of the organic derivatives. In this review, we introduce some examples of the use of water to perform organoselenium chemistry. We mainly discuss the advantages of this medium when the recyclability is demonstrated and when the water can control the ...

Deposition/Dissolution Battery Chemistry In article number 2204681, Guozhao Fang, Zhigao Luo, Shuquan Liang, and co-workers research the anion-modulated balance between thermodynamics dynamics of interfacial dissolution/deposition reaction chemistry. The combination fusion anions cations in upper lower half correspond to a buffering effect complexation effect, respectively, which enables batter...
