A PROCESS FOR THE REDUCTION OF CARBOXYLIC ACID HALIDES TO CORRESPONDING ALDEHYDES

摘要

Carboxylic acid halides are reduced to the corresponding aldehydes by the use of cadmium borohydride as reducing agent which can be prepared as a solution by mixing a cadmium salt with an alkali metal borohydride in an inert polar solvent. The process enables carboxylic acid halides to be reduced to aldehydes without the need to use catalytic hydrogenation and the need to use very low temperatures.
