摘要

Abstract: Aryl thiocyanates 3 (22 examples) were easily prepared by reaction of dry arenediazonium o-benzenedisulfonimides 1 and sodium thiocyanate (2) in anhydrous acetonitrile at room temperature (20-25 C) in the presence of copper powder (Procedure A) and at 50 C or room temperature without the metal catalyst (Procedure B). The yields were from very good to excellent in Procedure A (average yield= 83%), and from modest to ...
