Allylation of 4-amino-3-mercapto-6-methyl-4H-1,2,4-triazin-5-one (1) and its arylideneamino derivatives 5 was performed through two different methods. Reaction of 1 and 5 with allylic bromides 2 in the presence of sodium ethoxide afforded a mixture of S- and N-allylated products. Treatment of arylimines 5 with allylic zinc bromides 9 and triallylborane reagents 12 did not affect the hetero-ring opening
