摘要：

An efficient palladium nanoparticles-catalyzed N-arylation of sulfonamides and sulfonyl azides is described. This procedure serves as an active protocol for intermolecular C-N bond formation using Pd(OAc)(2) in PEG-400 under air. Aryl bromides and triflates react at 35 degrees C, while aryl chlorides require heating to 50 degrees C and give the desired products only in low yields. This reaction proceeds smoothly in acceptable yields using low catalyst loading.
