Abstract

Organohalides are dehalogenated by bringing an organohalide or a mixture of two or more organohalides into contact with an alkali hydroxide in an alcoholic solution and in the presence of a catalytically effective amount of a heterogeneous transfer hydrogenolysis catalyst.
The process can be carried out at relatively low temperatures (50° - 150°C )and at low pressures.
