摘要

The reaction of 2 with BNO, generated in situ from the benzhydroximic acid chloride and triethyl amine at 0°C, affords the following products after 24 h at room temperature: the dimerization products of BNO, unreacted 2-cyanophenol, expected 3-phenyl-5-(2-hydroxyphenyl)-1,2,4-oxadiazole (43%), 2-cyanophenyl benzoate (25%) deriving from the unstable O-(2-cyanophenyl) benzohydroxamate and several other products which were not characterized.
