Process for the catalytic halogenation of a diol

摘要

The present invention relates to a process for the catalytic halogenation of an organic compound comprising at least one vicinal diol moiety, said process comprising a step of bringing the organic compound comprising at least one vicinal diol moiety into contact with a hydrogen halide in the presence of a catalyst, characterized in that the catalyst is an organic compound comprising a beta-diketone moiety or a beta-keto aldehyde moiety.
