氧化系列物(nitrile oxides)1a-1n在開放系統下,可與三乙基硼(triethylborane)試劑反應進行自由基加成反應而生成(oxime)。反應機構首先由乙基自由基進行加成反應後再從水溶液中得到氫。此反應在含有氧氣的幫助下十分容易發生;而加入自由基之抑制劑如galvinoxyl時,則明顯地抑制或減少類的生成,其結果足以證明是屬於自由基的反應機構。
Reaction of nitrile oxides 1a-1n with triethylborane under the open system undergo free radical addition reaction to generate oxime. The mechanism is proposed to be a free-radical reaction via ethyl radical addition and then undergo protonlysis in aqueous solution. The reaction is stimulated by the presence of oxygen and is also retarded or inhibited by the presence of galvinoxyl in the solution.
