A simple and efficient method to synthesize N-chloro-N-sulfonylsulfinamides by the direct aminoxidation of arenethiols under aqueous and mild conditions is disclosed, geminally installing the oxo and amino groups on the sulfur atom of arenethiols. The products have been primarily developed as sulfinylation reagents to convert Grignard reagents into sulfoxides, and as amination reagents to convert secondary amines into hydrazine derivatives.
DABCO-bis (sulfur dioxide), DABSO, as a convenient source of sulfur dioxide for organic synthesis: Utility in sulfonamide and sulfamide preparation

supporting information; experimental part, p. 4876 - 4878 (2011/12/05)
The charge-transfer complex generated from the combination of DABCO and sulfur dioxide, DABSO, is a bench-stable colorless solid suitable for use in organic synthesis as a replacement for gaseous sulfur dioxide. The complex can be combined with Grignard reagents to form sulfinates, which can then be converted in situ to a series of sulfonamides. Alternatively, reaction with anilines and iodine leads to the formation of a series of sulfamides. Cheletropic addition between DABSO and 2,3-dimethylbutadiene provides the corresponding sulfolene.
(Arylsulfonyl)acetones and -acetonitriles: New activated methylenic building blocks for synthesis of 1,2,3-triazoles

β-Keto sulfones and b-nitrile sulfones were used as building blocks for 1,2,3-triazole synthesis in the Dimroth cyclization. It was shown, that sulfone reagents undergo base-catalyzed cyclization under mild conditions (at room temperature) to give 1,2,3-triazoles in moderate to excellent yields. This fact has confirmed the high nucleophilicity of sulfonylmethylenic compounds and allows new synthetic applications. Georg Thieme Verlag Stuttgart.
