A heterogeneous Chan-Lam coupling reaction between sulfonyl azides and arylboronic acids was achieved in MeOH at room temperature in the presence of 10 mol% of an l-proline-functionalized MCM-41-immobilized copper(i) complex [MCM-41-l-proline-CuCl] under air, yielding a variety of N-arylsulfonamides in excellent yields. The new heterogeneous copper complex can be prepared from commercially readily available and inexpensive reagents, and recovered by simple filtration of the reaction solution and recycled at least 8 times without any decreases in activity.

A new and mild synthetic approach for the synthesis of N-arylsulfonamides under copper-catalyzed conditions at room temperature has been developed. The reaction employs various tert-butyl N-sulfonylcarbamates and diaryliodonium salts to avoid potential genotoxic impurities. A one-pot coupling/Boc-deprotection sequence is also reported to provide mono N-arylsulfonamides in good to excellent yields.

A mild and efficient method for the synthesis of N-arylsulfonamides in the presence of 10 mol % of CuCl is demonstrated. The reaction proceeds readily at room temperature in an open flask using a variety of sulfonyl azides and boronic acids without any base, ligand, or additive.

experimental part, p. 143 - 148 (2010/11/16)
An efficient synthesis of N-arylsulfonamides with a variety of aryl bromides, aryl iodides and heteroaryl bromides using KF/Al2O 3 as a suitable base, CuI as an inexpensive catalyst and N,N′dimethylethylenediamine (N,N′-DMEDA) as an effective ligand is described. Indian Academy of Sciences.
