摘要: Abstract The reaction of 1,2-bis-(5-tetrazolyl)benzene or 1,2-bis-(5-tetrazo1y1)pyrazines with dibromoalkane in the presence triethylamine gave corresponding symmetric and asymmetric cycophanes. structure which was partially characterized by spectral (infrared, 1H-nmr) methods fully elucidated single crystal X-ray analysis.
