The syntheses of perfluorinated N-bromosuccinimide dOCF2CFzCONBr and perfluorinated N-bromoglutarimide bOCF2CF2CF2COhBr are described. The-CFzCO-groups attached to the nitrogen make tbe hydrogen very protonic in the imides and the bromine very positive in the N-bromoimides. Reaction with toluene at room temperature causes ring bromination only, while at 90" side chain and ring bromination occur to comparable extent. No reaction ...
