A kinetically controlled radical addition/elimination reaction generating fluorinated allenes was developed. This strategy offers a route to a facile synthesis of diverse trifluoromethyl, difluoromethylene, and perfluoroalkyl functionalized allenes from readily available fluoroalkyl halides and alkynyl aziridines under visible-light irradiation.

We report a new synthetic method for the synthesis of a family of dibenzodiazepines (DBDAs), employing Pd-catalyzed C–N coupling of o-bromoaldimine, with o-bromoaniline as the key step.
