Claims11
A process for preparing perhalogenated olefins, which comprises reacting a perhalogenated alkane containing at least two carbon atoms and having at least one halogen atom selected from the group consisting of chlorine, bromine and iodine wherein said halogen atom is on each of two adjacent carbon atoms, with a tris-dialkylamino phosphine of formula:
- P(NR.sub.1 R.sub.2).sub.3 (I)
- where R.sub.1 and R.sub.2 represent an alkyl group containing 1 to 4 carbon atoms, at temperatures not exceeding 60.degree. C.
