Descrizione generale

Sulfuryl chloride is a sulfur containing reagent. It is widely used for chlorination of various compounds, as it dissociates into sulfur dioxide and chlorine during reaction. Thus, it acts as a source of molecular chlorine for various aromatic chlorination reactions. Its chlorination reaction with dimethyl sulfide has been studied. Sulfuryl chloride may be used as an efficient reagent for the p-chlorination of phenols.

Applicazioni

Sulfuryl chloride (SO2Cl2) may be used in the following studies:
  • Synthesis of α-chloroketones.
  • Regioselective (ortho-selective) chlorination of phenols.
  • Conversion of monocyclic allylic cis-1,2-diols to the corresponding trans-1,2-chlorohydrins.
  • Preparation of β-chlorotetrahydrofuran derivatives.

Sulfuryl chloride may be used as an efficient reagent for the p-chlorination of phenols.

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
