4-Chlorobenzenesulfonyl chloride was used in the synthesis of precursors for the 3,4-pyridyne generation.?? ??
4-Chlorobenzenesulfonyl chloride is manufactured by mixing 4-chlorobenzene and chlorosulfuric acid at 35 ℃, heating for two hours at 80 ℃, and discharging the contents of the reactor into ice water; yield 81% of theory, together with a small amount of bis(4-chlorophenyl) sulfone.Purification Methods
Crystallise it from ether in powdered Dry-Ice, after the solution has been washed with 10% NaOH until colourless and dried (Na2SO4). Distil it in vacuo and store it in the absence of H2O. [Beilstein 11 IV 114.]4-???????? ??? ?? ?? ? ???
