Abstract
None:
A concise, metal-free denitrogenative cyclization of benzothiatriazines was developed for the efficient synthesis of seven-membered biaryl sultams. This method proceeds under simple thermal conditions and tolerates a broad substrate scope. The mechanistic study indicates that the reaction involves the formation of a diradical intermediate.

02:26Preparation and Reactions of Sulfides
5.7K
Sulfides are the sulfur analog of ethers, just as thiols are the sulfur analog of alcohol. Like ethers, sulfides also consist of two hydrocarbon groups bonded to the central sulfur atom. Depending upon the type of groups present, sulfides can be symmetrical or asymmetrical. Symmetrical sulfides can be prepared via an SN2 reaction between 2 equivalents of an alkyl halide and one equivalent of sodium sulfide.

Sulfonation of benzene is a reaction wherein benzene is treated with fuming sulfuric acid at room temperature to produce benzenesulfonic acid. Fuming sulfuric acid is a mixture of sulfur trioxide and concentrated sulfuric acid.
