The anhydride and acid chloride of tetrafluoroisonicotinic acid have been made and used to prepare substituted amides and hydrazines. NN′-Di(tetrafluoroisonicotinoyl)hydrazine undergoes cyclodehydration when treated with phosphoryl chloride or phosphorus pentasulphide, to give 2,5-di(tetrafluoro-4-pyridyl)-1,3,4-oxadiazole and -thiadiazole respectively. Tetrafluoroisonicotinoyl fluoride reacts with
The reactions of pentafluorophenylhydrazine and its β-ACYL derivatives with compounds of the CCl3R-type in the presence of AlCl3—a new method of obtaining of pentafluorophenyl-hydrazidoyl dichlorides and chlorides and the derivatives of Δ2-1,3,4-oxadiazolin-5-one
