摘要
在固-液相转移催化下,采用Curtius重排反应合成了一系列 芳香异氰酸酯。该法具有反应条件温和,操作简便,产率高等优点。
A new and simple method for the synthesis of Aromitic Isocyanates was developed by solid - liquid phase transfer catalysis with curtius rearrangement reaction. The method proposed has several advantages: manipulations are simple and reaction conditions are mild. The presence of water is completely avoided and yields in some instances are good.
