The metal free, direct oxidation of 2-, 3-, and 4-picoline to the corresponding carboxylic acid using either oxygen or air has been developed under continuous flow conditions. Complete conversion for all three substrates was obtained at moderate temperatures and pressures within minutes.
在连续流条件下,开发了一种无金属、直接将 2-、3-和 4-吡啶氧化为相应羧酸的方法,可使用氧气或空气。在温和的温度和压力下,所有三种底物都能在数分钟内完全转化。
