Benzaldehyde (C 6 H 5 CHO) is an organic compound consisting of a benzene ring with a formyl substituent. It is among the simplest aromatic aldehydes and one of the most industrially useful. It is a colorless liquid with a characteristic almond -like odor , and is commonly used in cherry -flavored sodas . [ 5 ]
The reaction is named after Russian organic chemist Vyacheslav Tishchenko, who discovered that aluminium alkoxides are effective catalysts for the reaction. [ 1 ] [ 2 ] [ 3 ] In the related Cannizzaro reaction , the base is sodium hydroxide and then the oxidation product is a carboxylic acid and the reduction product is an alcohol .
In the lab, phenyl-2-nitropropene is produced by the reaction of benzaldehyde and nitroethane in the presence of a basic catalyst like n-butylamine.The reaction is a nitroaldol reaction, and is a variant of a Knoevenagel condensation reaction, which is one of a broader class of reactions called Henry condensations, or simply Henry reactions.
In organic chemistry, the benzoin addition is an addition reaction involving two aldehydes (−CH=O). The reaction generally occurs between aromatic aldehydes or glyoxals (OCH=CHO), [1] [2] and results in formation of an acyloin (−C(O)CH(OH)−). In the classic example, benzaldehyde is converted to benzoin (PhCH(OH)C(O)Ph). [3]
1,2,3,6-Tetrahydrobenzaldehyde is an organic compound with the formula C 6 H 9 CHO. This colorless liquid is formally a partially hydrogenated derivative of benzaldehyde.It is produced by the Diels-Alder reaction of acrolein to butadiene.
Of its many reactions, 2-methylbenzaldehyde undergoes BF 3-induced Rothemund condensation with pyrrole to give atropoisomers of tetrakis(o-tolyl)porphyrin. [2] It is one of main benzaldehyde component of automobile exhaust. [3]
2-Carboxybenzaldehyde is a chemical compound.It consists of a benzene ring, with an aldehyde and a carboxylic acid as substituents that are ortho to each other. The compound exhibits ring–chain tautomerism: the two substituents can react with each other to form 3-hydroxyphthalide, a cyclic lactol.
