A '''sulfonyl''' group is an organic [[radical (chemistry)|radical]] or [[functional group]] obtained from a [[sulfonic acid]] by the removal of the [[hydroxyl]] group. Sulfonyl groups can be written as having the general formula R-S(=O)<sub>2</sub>-R', where there are two [[double bond]]s between the [[sulfur]] and [[oxygen]]. The names of sulfonyl groups typically end in -syl, such as in '''[[tosyl]] chloride''' which is p-toluenesulfonyl chloride, CH<sub>3</sub>C<sub>6</sub>H<sub>4</sub>SO<sub>2</sub>Cl or '''[[mesylate|mesyl]] chloride''' which is methylsulfonyl chloride, CH<sub>3</sub>SO<sub>2</sub>Cl. Sulfonyl groups can be reduced to the [[hydrocarbon]] with [[lithium aluminium hydride]] (LiAlH<sub>4</sub>).
