异氰酸酯的反应≠

我们研究了芳基和烷基异氰酸酯在消耗性镁阳极存在下的有机电解反应。芳基异氰酸酯电解得N,N’-二取代脲,烷基异氰酸酯则还原偶联为N,N’-二取代草酰胺。我们认为这是由于烷基异氰酸酯从阴极得到电子发生双分子偶联,芳基异氰酸酯则是与阴极析出的高分散的活性镁起作用。

We have studied the electroorganic reaction of aryl and alkyl isocyanate in the system of using sacrificial magnesium anode. Aryl isocyanate yielded N, N' - disubstituted urea and alkyl isocyanate yielded N,N' - disubstituted oximide. This is because of the coupling reaction between two alkyl compounds occurred by gaining electron from cathode, and aryl isocyanate reacted with high dispersed active magnesium on the cathode.
