本文研究了在液-液及固-液两相体系中(相转移催化条件)由脂肪族和芳香族酰胺及其N-溴代物经Hofmann重排生成异氰酸酯的反应,并且以较好的产率制得了异氰酸-3-庚酯的纯品。
In this paper, the reaction of isocyanates from Hofmann rearrangements of aliphatic and aromatic amides and their N-bromides in liquid-liquid and solid-liquid two-phase systems (phase transfer catalysis conditions) was studied and the better yields A pure product of 3-heptyl isocyanate was obtained.
