A new route for the synthesis of stable 3-alkyl- and 3-aryl-2(,2)-(di)fluoroaziridines was developed by hydride reduction of novel alpha-bromo- and alpha-chloro-alpha(,alpha)-(di)fluoroketimines and subsequent ring closure of beta-fluorinated beta-chloro- and beta-bromoamines. This is the first report on the synthesis of 2,2-difluoroaziridines sensu stricto.
