The addition of CH-active compounds to 6-aryl-1,2,4-triazine 4-oxide is reversible and occurs under conditions of kinetic control at position 5 of the heterocycle to form cyclic C(5)-σH adducts. Under conditions of thermodynamic control the nuc
Aromatic nucleophilic substitution in 1,2,4-triazine 4-oxides with Grignard reagents

Addition of the Grignard reagents to 1,2,4-triazine 4-oxides followed by aromatization of the intermediate σH-adducts by dehydrogenation or dehydration was used for synthesis of 5-alkyl- or 5-aryl-substituted 1,2,4-triazines and their 4-oxides.
