Synthesis of 2-nitrobenzaldehyde from 2-nitrotoluene

Solubilities of seven imidazoles (1imidazole, 2-methyl-1imidazole, benzimidazole, 2-methylbenzimidazole, 2-phenylimidazole, 4,5-diphenylimidazole, and 2,4,5-triphenylimidazole) in organic solvents (dichloromethane, 1-chlorobutane, toluene, and 2-nitrotoluene) have been measured using a synthetic method and liquid chromatography. The interactions of the imidazoles, benzimidazoles, or phenylimidazoles with different solvents are discussed. The solubilities of these imidazoles in chloroalkanes were very low. In all solvents studied, the solubility of phenylmidazoles was significantly lower than the solubility of 1-imidazole or benzimidazoles. Experimental results of solubility were correlated by means of the Wilson, UNIQUAC, and NRTL equations utilizing parameters derived from solid−liquid equilibria results. The existence of a solid−solid first-order phase transition in the solute has been taken into consideration in the solubility calculation. The best correlation of the solubility data was obtained by the Wilson equation with the average root-mean-square deviation equal to 3.2 K.

This product is further used for the synthesis of 2,4-dinitrotoluene and 2,4,6-trinitrotoluene.

Ahmed M. Tafesh was born in 1957 in Acre, Israel, and following his arrival in the United States in the fall of 1977, he received his B.S. degree in chemistry at Portland State University in 1981. In 1984 he received his M.S. at Oregon State University in the area of physical organic chemistry working on mechanistic investigation of conjugated carbenes with Professor Peter Freeman. He then moved east to Salt Lake City, where he received his Ph.D. in the area of free radical methodology development as well as the total synthesis of pseudomonic acid under the supervision of Professor Gary Keck. After graduation in 1989 he joined Hoechst Celanese Corp. in Corpus Christi, TX, as a Research Chemist working in exploratory research. In 1991 he was promoted to Research Chemist II and worked on the development of pharmaceutical intermediates. In 1993 he was promoted to Senior Research Chemist and in 1994 he was awarded a two year assignment in Hoechst AG Corporate Research in Frankfurt, Germany. In Germany, Ahmed was active in the area of development of oxidation reagents as well as the development of water soluble catalysts for the reductive carbonylation of aromatic nitro compounds. Ahmed holds more than 20 patents in different areas. Upon completion of his assignment, Ahmed will return to Texas for his new role as a group leader in the area of asymmetric catalysis.

Shiina macrolactonization or Shiina lactonization is an organic chemical reaction that. 1 Mechanism; 2 Details; 3 See also; 4 References; 5 External links. In the basic reaction, 2-methyl-6-nitrobenzoic anhydride MNBA is primarily used. and intermolecular reactions are used for the artificial synthesis of various natural.

On the other hand, deactivating substituents destabilize the intermediate cation and thus decrease the reaction rate. They do so by withdrawing electron density from the aromatic ring, though the positions most affected are again the ortho and para ones. This means that the most reactive positions (or, least unreactive) are the meta ones (atoms 3 and 5). Examples of deactivated aromatic rings are nitrobenzene, benzaldehyde and trifluoromethylbenzene. The deactivation of the aromatic system also means that generally harsher conditions are required to drive the reaction to completion. An example of this is the nitration of toluene during the production of trinitrotoluene (TNT). While the first nitration, on the activated toluene ring, can be done at room temperature and with dilute acid, the second one, on the deactivated nitrotoluene ring, already needs prolonged heating and more concentrated acid, and the third one, on very strongly deactivated dinitrotoluene, has to be done in boiling concentrated sulfuric acid.
