原始摘要（英文原文）· Original abstract
An efficient method for the synthesis of tetrazolo[1,5-a]quinolines from N-aryltetrazoles and alkynes has been developed. The reaction proceeds through double C-H activation under chelation-controlled Rh(III)-catalysis and tolerates various functional groups. The obtained tetrazolo[1,5-a]quinolines exhibit fluorescence over a wide range (320-480 nm) with quantum yields of up to 58%.
