Ultrasound-promoted synthesis of 3-trichloromethyl-5-alkyl(aryl)-1,2,4- oxadiazoles
The alternative synthesis of 12 1,2,4-oxadiazoles using ultrasound irradiation from trichloroacetoamidoxime and acyl chlorides is reported. Seven of them are novel compounds. The 3-trichloromethyl-5alkyl(aryl)-1,2,4- oxadiazoles have been synthesised in b
