bis(trichloromethyl)mercury

Reaction of Mercury(II) Chloride (HgBr2 has proven to be unreactive) with Sodium  Trichloroacetate (1:2 molar ratio) in dry monoglyme at reflux for 1 h affords bis(trichloromethyl)mercury as a crystalline  solid after purification.

Flame-dried glassware and an atmosphere of dry nitrogen are used for the reactions. Organomercury(II) compounds should be carefully handled and skin contact and inhalation should be particularly avoided. All reactions must be conducted in a well-ventilated hood.
