PESTICIDES LABELED WITH C-14 .2. SYNTHESIS OF PROPICONAZOLE LABELED IN 3 DIFFERENT POSITIONS

Propiconazole was labelled with C-14 in three different positions: in the benzene ring, in the position 5 of the dioxolane ring, and in the triazole ring. The synthesis of three new key intermediates (m-dichlor o[U-C-14]benzene], 1,2,4-[U-C-14]triazole, [1-C-14]-pentane-1,2-diol) were also elaborated.
