title: Synthesis of benzo-γ-sultams via the Rh-catalyzed aromatic C-H functionalization of diazosulfonamides.
abstract: An efficient synthesis of 1-aryl-benzo-γ-sultams, 1-aryl-1,3-dihydrobenzo[c]isothiazole-2,2-dioxides, was achieved in 65-99% yields via the Rh-catalyzed intramolecular aromatic C-H functionalization of N,N-diaryl diazosulfonamides with 0.5 mol% Rh2(oct)4 as the catalyst.
