NEW APPROACH TO THE SYNTHESIS OF 2,6-DIFLUOROBENZOYL ISOCYANATE AND ITS USE IN THE PREPARATION OF N-(2,6-DIFLUOROBENZOYL)-N'-(POLYFLUOROARYL)UREAS

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. Keywords: 2,6-difluorobenzoyl chloride, trimethylsilyl isocyanate, 2,6-difluorobenzoyl isocyanate, polyfluoroaromatic amines, N-(2,6-difluorobenzoyl)-N'-(polyfluoroaryl)ureas, insect chitin biosynthesis inhibitors.
