ABSTRACT:
A new process for preparing haloalkyl epoxides and oxaziranes is described in which a mixture of an perhalo alkene or alkyl imine and chlorine gas is contacted with a Group IA, IIA metal oxide, carbonate or bicarbonate under mild conditions of temperature and pressure. The process, using perhalo alkenes or perhalo alkyl imines as starting material, represents a new economical, facil preparation of the monomer hexafluoropropylene oxide, such monomer is capable of polymerizaton or copolymerization to thermally stable and inert polymers.
