  描述：

  1-(phenoxy-bistrimethylsilyl-methyl)-1H-benzotriazole 在 四丁基氟化铵 、 lithium diisopropyl amide 作用下， 以 四氢呋喃 、 正己烷 为溶剂， 反应 3.0h， 生成 1-(adamatylidene-pheoxy-methyl)-4-trimethylsilyl-1H-benzotriazole

  名称：

  A general synthesis of 1-(1-alkenyl)benzotriazoles

  摘要：

  1-Methyl, 1-(alkoxymethyl) and 1-(trimethylsilylmethyl)benzotriazoles are metallated at the alpha-carbon. Trapping of the resulting metallated species with chlorotrimethylsilane gives compounds which undergo Peterson olefination even with hindered ketones. In some cases, metallation at the 4-position of the benzotriazole is observed. An exhaustive metallation/silylation sequence gives 4-trimethylsilyl substituted 1-benzotriazoles in good yields.
