The compound is prepared by the chlorsulfonation of benzene: C 6 H 6 + 2SHO 3 SCl → C 6 H 5 SO 2 Cl + HCl + SO 3. Benzenesulfonic acid is an intermediate in this conversion. Diphenylsulfone is a side product. Benzenesulfonyl chloride can also be prepared by treating benzenesulfonate salts with phosphorus oxychloride. [2]
Benzenesulfonic acid (conjugate base benzenesulfonate) is an organosulfur compound with the formula C 6 H 6 O 3 S.It is the simplest aromatic sulfonic acid.It forms white deliquescent sheet crystals or a white waxy solid that is soluble in water and ethanol, slightly soluble in benzene and insoluble in nonpolar solvents like diethyl ether.
Diphenylamine is an organic compound with the formula (C 6 H 5) 2 NH. The compound is a derivative of aniline, consisting of an amine bound to two phenyl groups. The compound is a colorless solid, but commercial samples are often yellow due to oxidized impurities. [5]
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.
N-tert-Butylbenzenesulfinimidoyl chloride reacts with enolates, amides, and primary alkoxides by the same general mechanism. The Swern oxidation , which converts primary and secondary alcohols to aldehydes and ketones, respectively, also uses a sulfur-containing compound ( DMSO ) as the oxidant and proceeds by a similar mechanism.
The original synthesis of PAES involved electrophilic aromatic substitution of an diaryl ether with the bis (sulfonyl chloride) of benzene. Reactions typically use a Friedel-Crafts catalyst, such as ferric chloride or antimony pentachloride: n O(C 6 H 5) 2 + n SO2Cl2 → {[O(C 6 H 4) 2]SO 2} n + 2n HCl
Benzotrichloride (BTC), also known as α,α,α-trichlorotoluene, phenyl chloroform or (trichloromethyl)benzene, is an organic compound with the formula C 6 H 5 CCl 3. Benzotrichloride is an unstable, colorless or somewhat yellowish, viscous, chlorinated hydrocarbon with a penetrating odor.
This chloride undergoes dehydrochlorination to afford the target: CH 3 CH(Cl)PO(OH) 2 → CH 2 =CHPO(OH) 2 + HCl In the Kinnear–Perren reaction alkylphosphonyl dichlorides and esters are generated by alkylation of phosphorus trichloride in the presence of aluminium trichloride .
