A novel and efficient approach to sulfonamides has been developed. Using TBHP as the oxidant and NH4I (20 mol%) as the catalyst, arylsulfonyl hydrazides reacted with amines to provide sulfonamides in moderate to good yields. Possible reaction pathway for the formation of the products was also discussed in this paper. Sulfonimides were synthesized through the oxidation coupling of arylsufonylhydrazides and amines by TBHP/NH4I system in moderate to good yields.

A new synthesis of sulfonamides has been developed via an iodine-catalyzed sulfonylation of amines with arylsulfonyl hydrazides. This metal-free strategy employs readily accessible and easy to handle starting materials, catalysts and oxidants, and can be easily conducted under mild conditions, providing a convenient access to a wide range of sulfonamides in moderate to excellent yields within a short reaction time.

The iodine-catalyzed oxidative amination of sodium sulfinates in the presence of sodium percarbonate as the oxidant has been developed. The reaction shows good substrate scope and tolerates a wide range of functionalities in both amine and sodium sulfinate substrates. Aliphatic amines, heteroaromatic amines and hydrochloride salts of amines canbe employed as the amine sources in this transformation. Mechanistic studies indicated that a radical pathway might be involved in the reaction process. This transition-metalfree protocol offers an alternative and convenient approach for a preparation of a series of sulfonamides in moderate to good yields under mild conditions.
DABCO-bis (sulfur dioxide), DABSO, as a convenient source of sulfur dioxide for organic synthesis: Utility in sulfonamide and sulfamide preparation
Woolven, Holly,Gonzalez-Rodriguez, Carlos,Marco, Isabel,Thompson, Amber L.,Willis, Michael C.
, 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.
An improved synthesis of 1,4,7-triazacyclononanes (tacns) and 1,4,7,10-tetraazacyclododecanes (cyclens)

experimental part, p. 2341 - 2344 (2010/02/28)
Reaction of tosylbis[2-(tosyloxy)ethyl]amine with ethylenediamine gives 1-tosyl-1,4,7-triazacyclononane in good yield. A similar reaction of tosylbis[2-(tosyloxy)ethyl]amine with diethylenetriamine gives 1-tosyl-1,4,7,10-tetraazacyclododecane. These tosyl
