General description
磺酰氯是一种含硫试剂。它广泛用于各种化合物的氯化，因为它在反应过程中分解成二氧化硫和氯。因此，它作为各种芳族氯化反应的分子氯来源。人们对其与二甲硫的氯化反应进行了研究。磺酰氯可用作苯酚的对氯氯化反应的有效试剂。
Application

2,2,6,6-Tetramethylpiperidine (TMP)-catalyzed (1-10%) chlorinations of phenols by SO2Cl2 in aromatic solvents are more ortho selective than with primary and less hindered secondary amine catalysts. Ortho-selective chlorination is successful even with electron deficient phenols such as 2-hydroxybenzaldehyde and 2'-hydroxyacetophenone. Notably, ortho

Monocyclic allylic cis-1,2-diols reacted with sulfuryl chloride at 0 °C in a regio- and stereo-selective manner to give 2-chloro-1-sulfochloridates, which were hydrolysed to yield the corresponding trans-1,2-chlorohydrins. At -78 °C, with very slow addition of sulfuryl chloride, cyclic sulfates were
