The formation of the tris(3-benzyl-triazol-5-yl)carbenium cation, a heterocyclic analogue of the trityl cation, from tris(3-benzyl-triazol-5-yl)methanol, itself generated by Cu(I)-catalyzed Huisgen reaction of benzyl azide with triethynylmethanol, in the presence of trifluoroacetic anhydride is evidenced through a selective SN1 reactivity with various O-, N-, S-, and C-nucleophiles, giving the corresponding
由三(3-苄基-三唑-5-基)甲醇本身生成的三(3-苄基-三唑-5-基)碳鎓阳离子,三苯甲基阳离子的杂环类似物,本身由Cu(I)-生成在三氟乙酸酐存在下,苄基叠氮化物与三乙炔基甲醇催化的惠斯根反应通过与各种O-,N-,S-和C-亲核试剂的选择性S N 1反应来证明,从而以中等至高收率提供了相应的三唑基甲烷衍生物。
