✦ Synopsis

Acyl chlorides are split into acyl and chlorine radicals by light of wavelength 254 my. Since the dissociation energy of the chlorine-hydrogen bond is considerably larger than that of the acyl-hydrogen bond, substitution of the substrate by acyl radicals is observed on irradiation of acid chlorides. On irradiation of acetyl chloride the following reactions take place: BrZ CC14 Brz CHCI, BrZ CKCHhCI IC1 CI(CH2)zCI 12 CHCI,

Thermal reactions of 3-phenyl-5-arylamino-1,2,4-oxadiazoles I and II were investigated. Neat heating at ca. 250ЊC for 6 hours afforded H 2 O, benzonitrile, arylcyanamides, arylamines, azobenzene, benzimidazole derivatives, and 3,3Ј-diphenyl-5,5Ј-bis[1,2,4-oxadiazolyl].
