As we were also interested in the synthesis of N-bridged diaryliodonium salts, we additionally investigated N-tosylsulfonamide 7a with 4a as aryne source under slightly different conditions for the arylation step (Scheme 3). The desired product 2a was obtained in a high yield of 92% without any further optimizations. Therefore, we started to investigate the scope and the scalability of this reaction. Performing the reaction on a 5 mmol scale gave 2a in a slightly improved yield of 96%.
