Abstract Treatment of O‐alkylhydroxylamine hydrochlorides with 2‐acyl‐4,5‐dichloropyridazin‐3(2H)‐ones in the presence of triethylamine or Amberlite® IRA‐67 in acetonitrile gave corresponding O‐alkylhydroxamic acid derivatives in excellent yields. This is an efficient, convenient, and eco‐friendly method.
摘要 在乙腈中存在三乙胺或 Amberlite® IRA-67 的情况下,用 2-酰基-4,5-二氯哒嗪-3(2H)-酮处理 O-烷基羟胺盐酸盐,以优异的收率得到相应的 O-烷基异羟肟酸衍生物。这是一种高效、方便且环保的方法。
