4,4’-Dichlorobenzophenone is prepared by the acylation of chlorobenzene with 4-chlorobenzoyl chloride. The conversion is typically conducted in the presence of an aluminium chloride catalyst in a petroleum ether solvent. ClC 6 H 5 C(O)Cl + C 6 H 5 Cl → (ClC 6 H 4) 2 CO + HCl
In enzymology, a 4-chlorobenzoyl-CoA dehalogenase (EC 3.8.1.7) is an enzyme that catalyzes the chemical reaction. 4-chlorobenzoyl-CoA + H 2 O 4-hydroxybenzoyl CoA + chloride. Thus, the two substrates of this enzyme are 4-chlorobenzoyl-CoA and H 2 O, whereas its two products are 4-hydroxybenzoyl CoA and chloride.
The benzoyl functional group.. 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.
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 .
This produces 2,4,6-trichlorobenzoic acid, which can then be refluxed in thionyl chloride to form 2,4,6-trichlorobenzoyl chloride. [ 4 ] Since 2,4,6-trichlorobenzoic acid is produced as a by product of the Yamaguchi esterification process, it can be refluxed again to recreate 2,4,6-trichlorobenzoyl chloride.
The 2,4,6- isomer is easily produced by deprotonation of 1,3,5-trichlorobenzene followed by reaction with carbon dioxide. [1] Its conversion to 2,4,6-trichlorobenzoyl chloride makes it a key intermediate in the Yamaguchi esterification protocol.
In enzymology, a 4-chlorobenzoate—CoA ligase (EC 6.2.1.33) is an enzyme that catalyzes the chemical reaction. 4-chlorobenzoate + CoA + ATP 4-chlorobenzoyl-CoA + AMP + diphosphate. The 3 substrates of this enzyme are 4-chlorobenzoate, CoA, and ATP, whereas its 3 products are 4-chlorobenzoyl-CoA, AMP, and diphosphate.
mCPBA can be prepared by reacting m-chlorobenzoyl chloride with a basic solution of hydrogen peroxide, followed by acidification. [3]It is sold commercially as a shelf-stable mixture that is less than 72% mCPBA, with the balance made up of m-chlorobenzoic acid (10%) and water. [1]
