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.degree.-150.degree. C.) and at low pressures. No added hydrogen is employed, in excess of that contained in the ambient atmosphere.

Process for the dehalogenation of organic compounds

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.degree.-150.degree. C.) and at low pressures.

There is provided a process for the production of aldehydes wherein an oric halide is reacted with carbon monoxide at a superatmospheric pressure in the presence of a hydrogen donor and in the presence of a base and of a catalyst in a solvent system. Catalysts of choice are transition metal catalysts. A preferred temperature range is from about 50.degree. to 150.degree. C.
