Fluorinated Heterocyclic Compounds. A Photochemical Approach to a Synthesis
Polyfluoroaryl-1,2,4-triazoles. — Photolysis of 1,2,4-oxadiazoles (I) results in
24- 123 of
O—N bond cleavage which reacts with nucleophiles (II) to form cyclized 1,2,4-triazoles (IV). Application of the method to the perfluoroalkyl derivative results in a
different reaction pathway yielding the perfluoroalkyl amide (IX). — (BUSCEMI*,
