5]imidazo[1,2-d][1,2,4]triazine 4a–4w were designed and conveniently synthesized via the intermediates 2-(halogenated alkyl)-1H-benzo[d]imidazoles 2a, 2b, and 2-((1-(substituted phenyl)hydrazinyl)alkyl)-1H-benzo[d]imidazoles 3a–3g. The structures of all target compounds were characterized by FT-IR, 1H NMR, 13C NMR, and EI-MS, of which, the structure of compound 4n was further determined by the single crystal
通过中间体2-(卤代烷基)-1H-设计并方便地合成了一系列带有苯并[4,5]咪唑并[1,2-d][1,2,4]三嗪4a-4w的新型稠合杂环化合物苯并[d]咪唑2a、2b和2-((1-(取代苯基)肼基)烷基)-1H-苯并[d]咪唑3a-3g。所有目标化合物的结构均经FT-IR、1H NMR、13C NMR和EI-MS表征,其中化合物4n的结构进一步通过单晶X射线衍射确定。4n的晶体结构在三斜晶系中结晶,空间群P1¯ a = 9.033 (6) Å, b = 10.136 (7) Å, c = 10.396 (7) Å, α = 118.323 (7)°, β = 91.750 (8)°, γ = 104.198 (7)°, Z = 2, V = 800.2 (9) Å3; 总 R 指数:R1 = 0.0475,wR2 = 0.1284。评价了标题化合物 4a-4w 对植物病原真菌 Botrytis
