摘要
Novel mono- and symmetrical di-N-hydroxy- and N-aminoguanidines were readily prepared from the reaction of diverse hydroxylamines or hydrazines with reagent classes di(benzotriazol-1-yl) methanimine 6, (bis-benzotriazol-1-yl-methylene) amines 8a, b, benzotriazole-1-carboxamidines 10a-i, benzotriazole-1-carboximidamides 11a,b, and N'-hydroxy-1H-1,2,3-benzotriazole-1-carboximidamide 18. The preparation is described for a variety of N-hydroxy- and N-aminoguanidines with different substitution patterns in good yields.
