(from acetonitrile). Calculated,%: N 7.55. . Found,%: K 7.90. In the IR spectra of Phenacyl- (3-phenyl-l, 2, 4-oxadiazolyl-5) ketones, there are two absorption bands, which are detected by the vibrations of two carbonyls in the / S, position, in Region 1530-1550 1580 -1600 s. In the IR spectra, there are no absorption bands in the region of 3000-3600 cm. Caused by the stretching vibrations of the on- and CN groups. “Nn-24-oxadiazolyl-5) ketone has two absorption maxima around 232 nm and 364 im.
