Long-Range Fluorine-Proton Coupling in 1,2,4-Triazole Derivatives

Several 1,2,4-triazole derivatives containing a 2-fluorophenyl substituent at either the 3- or 5-position and a methyl group at the 4-position were synthesized.These derivatives exhibit long-range 19F-1H and 19F-13C through-space coupling in their 1H and
