Abstract

A process for the selective dehydrofluorination of hydrochlorofluoroalkanes and novel hydrochlorofluoroalkenes is described wherein an effective amount of a catalytically active metal compound is applied which is selected from the group consisting of AlF3−δ, MgAlxF2+3x−δ and MgZryF2+4y−δ, wherein x and y have, independently of one another, values in the range of from 0 to 0.33 and δ has a value in the range of from 0 to 0.1. Certain hydrofluorochloroalkenes are also described, as well as their use as intermediates in chemical reactions.
