aryltrichloromethanes. Further transformations of the oximes in the reaction course can result in the formation of nitriles or 3,5-diaryl-1,2,4-oxadiazoles as final products. The conversion depth depends on reaction conditions and structures of trichloromethyl-arenes. When hydrazines used instead of hydroxylamine, respectivebenzaldehyde hydrazones or azines are obtained.
