Abstract
The invention relates to a method for producing diazoalkanes, which is characterized by dissolving a diazoalkane precursor in a first solvent, dissolving a base in a second solvent, allowing the substances to react in a reactor while forming the diazoalkane and removing the diazoxaline under reduced pressure. The inventive method is especially suitable for producing diazomethane.
