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 AIF3-δ, MgAl x F2+3x-δ and MgZr y F2+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. |
