Benzoyl chloride, also known as benzenecarbonyl chloride, is an organochlorine compound with the formula C 7 H 5 ClO. It is a colourless, fuming liquid with an irritating odour, and consists of a benzene ring ( C 6 H 6 ) with an acyl chloride ( −C(=O)Cl ) substituent .
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 − ...
Benzylic halides are typically strong alkylating agents, and for this reason benzal chloride is treated as a hazardous compound. Treatment of benzal chloride with sodium gives stilbene. Most benzal chloride main industrial use is as a precursor to benzaldehyde. This conversion involves hydrolysis in the presence of base: [2]
Amygdalin 2 H 2 O HCN benzaldehyde 2 × glucose 2 × Benzaldehyde contributes to the scent of oyster mushrooms (Pleurotus ostreatus). Reactions Benzaldehyde is easily oxidized to benzoic acid in air at room temperature, causing a common impurity in laboratory samples. Since the boiling point of benzoic acid is much higher than that of benzaldehyde, it may be purified by distillation. Benzyl ...
2- and 4-chlorotoluene are precursors to the corresponding benzyl chloride (ClC 6 H 4 CH 2 Cl), benzaldehyde (ClC 6 H 4 CHO), and benzoyl chloride (ClC 6 H 4 C(O)Cl). [2] 2- and 4-chlorotoluenes are converted to 2-chlorobenzonitrile and 4-chlorobenzonitrile, respectively. [3] Chlorotoluenes are precursors to dichlorotoluenes.
The benzoyl group is often abbreviated "Bz" (not to be confused with "Bn," which is used for benzyl), thus benzoic acid is also denoted as BzOH, since the benzoyl group has the formula – C 6 H 5 CO. It is the simplest aromatic carboxylic acid. The name is derived from gum benzoin, which was for a long time its only source.
In the classic example, benzaldehyde is converted to benzoin (PhCH(OH)C(O)Ph). [3] The benzoin condensation was first reported in 1832 by Justus von Liebig and Friedrich Wöhler during their research on bitter almond oil. [4] The catalytic version of the reaction involving cyanide was developed by Nikolay Zinin in the late 1830s. [5] [6 ...
The Sommelet reaction is an organic reaction in which a benzyl halide is converted to an aldehyde by action of hexamine and water. [1] [2] It is named after the French chemist Marcel Sommelet, who first reported the reaction in 1913. [3] One example, thiophene-2-carboxaldehyde is prepared by the reaction of hexamine with 2-chloromethylthiophene ...
