O-Nitroanisole

	O-Nitroanisole ''o''-Nitroanisole is an organic compound with the formula CH3OC6H4NO2. Three isomers of nitroanisole exist, but the o-isomer is the most commercially important. It is a colorless liquid. It is prepared by treatment of ''o''-chloronitrobenzene with sodium methoxide Sodium methoxide is the simplest sodium alkoxide. With the formula , it is a white solid, which is formed by the deprotonation of methanol. Itis a widely used reagent in industry and the laboratory. It is also a dangerously caustic base. P ...: :NaOCH3 + ClC6H4NO2 → CH3OC6H4NO2 + NaCl The resulting 2-chloronitrobenzene can reduced to o-anisidine, which is a precursor to dyes.

	2-Nitrochlorobenzene 2-Nitrochlorobenzene is an organic compound with the formula ClC6H4NO2. It is one of three isomeric nitrochlorobenzenes.Gerald Booth, "Nitro Compounds, Aromatic" in ''Ullmann's Encyclopedia of Industrial Chemistry'', Wiley-VCH: Weinheim, 2005. It is a yellow crystalline solid that is important as a precursor to other compounds due to its two functional groups. Synthesis Nitrochlorobenzene is typically synthesized by nitration of chlorobenzene in the presence of sulfuric acid: :C6H5Cl + HNO3 → O2NC6H4Cl + H2O This reaction affords a mixture of isomers. Using an acid ratio of 30/56/14, the product mix is typically 34-36% 2-nitrochlorobenzene and 63-65% 4-nitrochlorobenzene, with only about 1% 3-nitrochlorobenzene. Reactions Alkylation and electrophilic aromatic substitution can occur at the chlorinated carbon center, and a diverse array of reactions can be carried out using the nitro group. 2-Nitrochlorobenzene can be reduced to the 2-chloroaniline with Fe/HCl mixture, th ...

	Organic Compound In chemistry, organic compounds are generally any chemical compounds that contain carbon-hydrogen or carbon-carbon bonds. Due to carbon's ability to catenate (form chains with other carbon atoms), millions of organic compounds are known. The study of the properties, reactions, and syntheses of organic compounds comprise the discipline known as organic chemistry. For historical reasons, a few classes of carbon-containing compounds (e.g., carbonate salts and cyanide salts), along with a few other exceptions (e.g., carbon dioxide, hydrogen cyanide), are not classified as organic compounds and are considered inorganic. Other than those just named, little consensus exists among chemists on precisely which carbon-containing compounds are excluded, making any rigorous definition of an organic compound elusive. Although organic compounds make up only a small percentage of Earth's crust, they are of central importance because all known life is based on organic compounds. Living t ...

	Sodium Methoxide Sodium methoxide is the simplest sodium alkoxide. With the formula , it is a white solid, which is formed by the deprotonation of methanol. Itis a widely used reagent in industry and the laboratory. It is also a dangerously caustic base. Preparation and structure Sodium methoxide is prepared by treating methanol with sodium: : The reaction is so exothermic that ignition is possible. The resulting solution, which is colorless, is often used as a source of sodium methoxide, but the pure material can be isolated by evaporation followed by heating to remove residual methanol. As a solid, sodium methoxide is polymeric, with sheet-like arrays of centers, each bonded to four oxygen centers. The structure, and hence the basicity, of sodium methoxide in solution depends on the solvent. It is a significantly stronger base in DMSO where it is more fully ionized and free of hydrogen bonding.
