Abstract

A series of 1, 4-diphenyl-1, 2, 3-triazole-incorporated amide derivatives have been designed and prepared. X-ray crystallographic and (1D and 2D) 1H NMR studies reveal that these compounds fold into stable U-shaped conformations driven by three-center intramolecular C– H··· O hydrogen-bonding formed between the triazole C-5 H atom and the two ether O atoms. Such folded structures make this 1, 4-diphenyl-1, 2, 3-triazole skeleton a good ...
