| 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. |
| 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. |
