Descripción

General description

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.

Application

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.
