Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 616-43-3, is researched, SMILESS is CC1=CNC=C1, Molecular C5H7NJournal, Gazzetta Chimica Italiana called Oxidation of mono- and dimethylpyrroles, Author is Gardini, Gian P.; Bocchi, Vittorio, the main research direction is pyrrole methyl oxidation hydrogen peroxide; methylpyrrole oxidation hydrogen peroxide.Recommanded Product: 3-Methyl-1H-pyrrole.

Reaction of 30% H2O2 with N-methylpyrrole gave 27% N-methyl-2-oxo-2,5-dihydropyrrole (I) R = Me, R1 = H). 2-methylpyrrole gave with 1 mole H2O2 42% hydroperoxide (II, R = H) and with 2 moles H2O2 22% peroxide (III, R = H); 3-methylpyrrole gave 53% I (R = H, R1 = Me); 2,3 dimethylpyrrolc gave IV, and 2,4-dimethylpyrrole gave with 1 mole H2O2 53% II (R = Me) and with 2 moles H2O2, III (R = Me), V, and VI.

The article 《Oxidation of mono- and dimethylpyrroles》 also mentions many details about this compound(616-43-3)Recommanded Product: 3-Methyl-1H-pyrrole, you can pay attention to it, because details determine success or failure

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 5,6-Dichloropyrazine-2,3-dicarbonitrile, is researched, Molecular C6Cl2N4, CAS is 56413-95-7, about Preparation, Electronic and Liquid Crystalline Properties of Electron-Accepting Azaacene Derivatives.Synthetic Route of C6Cl2N4.

A series of electron-accepting azaacene-type materials with different kinds and degrees of intermol. interactions were synthesized. Simple modification of the terminal substituents significantly modulated the photophys. and electrochem. properties. The degree of the weak intermol. interaction determined the emergence of a liquid crystalline (LC) phase for each compound Dipole-dipole interaction, π-π interaction and van der Waals interaction all contributed to stabilize the LC phase of I [R = C6H13, C12H25, C18H37] and II. The introduction of strong hydrogen bonding interaction enabled the formation of a highly ordered LC phase in III. Charge-transport properties of I, II and III were also investigated.

Different reactions of this compound(5,6-Dichloropyrazine-2,3-dicarbonitrile)Synthetic Route of C6Cl2N4 require different conditions, so the reaction conditions are very important.
