Sulfonyl group - Wikipedia
In organosulfur chemistry, a sulfonyl group is either a functional group found primarily in sulfones, or a substituent obtained from a sulfonic acid by the removal of the hydroxyl group, similarly to acyl groups.
Sulfonyl halide - Wikipedia
In chemistry, a sulfonyl halide consists of a sulfonyl (>S(=O) 2) group singly bonded to a halogen atom. They have the general formula RSO 2 X, where X is a halogen. The stability of sulfonyl halides decreases in the order fluorides > chlorides > bromides > iodides, all four types being well known. The sulfonyl chlorides and fluorides are of ...
Sulfonic acid - Wikipedia
In organic chemistry, sulfonic acid (or sulphonic acid) refers to a member of the class of organosulfur compounds with the general formula R−S(=O) 2 −OH, where R is an organic alkyl or aryl group and the S(=O) 2 (OH) group a sulfonyl hydroxide. [1] …
Sulfonyl Group - an overview | ScienceDirect Topics
A sulfonyl group is defined as a common protecting group used in chemistry to protect pyrrole at nitrogen due to its strong electron-withdrawing effect, which reduces the reactivity of pyrrole and allows for a wider range of reactions with higher yields in regioselective alkenylation and acylation at specific positions.
Sulfonyl - an overview | ScienceDirect Topics
The sulfonyl chloride derivative allows simple conjugation of these molecules with proteins and other amine-containing compounds. The derivative is prepared by reaction of the sulfonate with thionyl chloride or phosphorus pentachloride in non-aqueous conditions.
Sulfonyl Group - (Organic Chemistry) - Vocab, Definition ...
The sulfonyl group (−SO2−) is a functional group consisting of a sulfur atom double-bonded to two oxygen atoms. It is an important moiety in organic chemistry, particularly in the context of the synthesis of polysubstituted benzenes.
