| The '''Reed reaction''' is a [[chemical reaction]] that utilizes [[photochemistry|light]] to [[redox|oxidize]] [[hydrocarbon]]s to [[sulfonyl chloride]]s. The reaction performs via the [[free radicals]]. First, the light makes a molecule of [[chlorine]] dissociate [[homolysis (chemistry)|homolytically]], then a chlorine atom produced attacks the hydrocarbon chain to form [[hydrogen chloride]] what results in the formation of [[alkyl]] free radical. Then [[Sulfur dioxide|SO<sub>2</sub>]] as an [[electron donor]] bonds to the [[reaction center]], forming an [[sulfonyl]] radical. Finally, the least one attacks another chlorine molecule to produce a sulfonyl chloride and a new chlorine atom which continues the reaction chain. | | The writer's name is Christy.

| Chain initiation:
| |
| ::::<math>Cl_2 \xrightarrow{h\nu} 2Cl\cdot </math>
| |
| | |
| Chain propagation steps:
| |
| ::::<math>R-H + \cdot Cl \longrightarrow R \cdot + HCl</math> | |
| ::::<math>R\cdot + :\!SO_2 \longrightarrow R- \dot{S} O_2</math>
| |
| ::::<math>R- \dot{S} O_2 + Cl_2 \longrightarrow R-SO_2-Cl + Cl \cdot </math>
| |
| | |
| The resulting sulfonyl chlorides are widely used in the [[detergent]] industry as a [[raw material]].
| |
| | |
| Under particular circumstances (40–80 °C) only [[halogenation|chlorination]] of alkane may take place.
