New approach to the synthesis of 2,6-difluorobenzoyl isocyanate and its use in the preparation of N-(2,6-difluorobenzoyl)-N?-(polyfluoroaryl)ureas
摘要:
The treatment of 2,6-difluorobenzoyl chloride with trimethylsilyl isocyanate gave 2,6-difluorobenzoyl isocyanate. This product reacts with polyfluoroaromatic amines to give the corresponding N-(2,6-difluorobenzoyl)-N'-(polyfluoroaryl) urea, which hold potential as inhibitors for the biosynthesis of insect chitin.
