一般說明

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。

應用

磺酰氯（SO2Cl2）可用于以下研究：
  • α-氯酮的合成。
  • 酚的特定选择（邻位选择）氯化。
  • 单环烯丙基顺式-1,2-二醇转化为相应的反式-1,2-氯代醇。
  • β-氯四氢呋喃衍生物的制备。

磺酰氯可用作苯酚的对氯氯化反应的有效试剂。

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

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
