eller et alkalimetalsalt heraf, i hvilken hvert Hal hver for sig repræsenterer et chloratom eller bromatom, omsættes med et alkalimetalhy-droxid, hvor reaktionen finder sted i opløsning eller i suspension i en organisk væskefase med en dielektricitets konstant på mindre end 10. Den resulterende forbindelse er et nyttigt mellemprodukt til syntesen af visse pyrethroidinsecticider.
