1-allyl-2-amino-1H-benzimidazole and 3-alkyl-(benzyl)-1-allyl-2-amino-1H-benzimidazolium halides was studied. The resulting 1-(2-bromopropyl) derivatives were subjected to thermolysis under different conditions, and the structure of dehydrobromination products was determined and proved by independent synthesis via prototropic isomerization of the allyl group by the action of bases.
研究了在1-烯丙基-2-氨基-1 H-苯并咪唑和3-烷基-(苄基)-1-烯丙基-2-氨基-1 H-苯并咪唑卤化物的双键处加氢溴化氢的方法。将得到的1-(2-溴丙基)衍生物在不同条件下进行热解,确定脱氢溴化产物的结构,并通过在碱的作用下通过烯丙基的质子异构化独立地合成来证明脱氢溴化产物的结构。
