Benzaldehyde oxime is an organic compound with the formula C 7 H 7 NO. Benzaldehyde oxime can be synthesized from benzaldehyde and hydroxylamine hydrochloride in presence of a base. The reaction at room temperature in methanol gives 9% E -isomer and 82% Z -isomer.
In organic chemistry, benzoyl (/ ˈ b ɛ n z oʊ ɪ l /, BENZ-oh-il) [1] is the functional group with the formula −COC 6 H 5 and structure −C(=O)−C 6 H 5. [2] [3] It can be viewed as benzaldehyde missing one hydrogen. The benzoyl group has a mass of 105 amu. The term "benzoyl" should not be confused with benzyl, which has the formula − ...
In organic chemistry, an oxime is an organic compound belonging to the imines, with the general formula RR’C=N−OH, where R is an organic side-chain and R' may be hydrogen, forming an aldoxime, or another organic group, forming a ketoxime. O-substituted oximes form a closely related family of compounds.
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 ]
2-Chlorobenzaldehyde (o-chlorobenzaldehyde) is an organic compound with the formula ClC 5 H 4 CHO. It is one of three isomeric monochlorinated benzaldehyde. 3-Chlorobenzaldehyde and 4-chlorobenzaldehyde are the other isomers. Whereas benzaldehyde is prone to autoxidation, the 2-chloro derivatives are more air-stable.

In the laboratory it can be prepared by the dehydration of benzamide or benzaldehyde oxime [2] or by the Rosenmund–von Braun reaction using cuprous cyanide or NaCN/DMSO and bromobenzene. Hydrogenation of benzonitrile in principle gives benzylamine, but owing to transamination, dibenzylamine and tribenzylamine are also produced.
For industrial applications the chemical is synthesized from p-cresol using aromatic substitution with bromine followed by nucleophilic substitution with sodium methoxide. [1] Oxidation of the methyl group to an aldehyde can occur via various synthetic methods.
