Abstract A highly efficient strategy was developed for the straightforward synthesis of tetraaryl-substituted pyrazoles. The cascade process consists of a regioselective 1,3-dipolar cycloaddition of benzosultam-3-ylidenes with nitrile imines and a subsequent elimination of SO2. The title compounds exhibit high fluorescence quantum yields and Aggregation Induced Emission (AIE) characteristics.
