Abstract

[6795-81-9] C2Cl6Hg (MW 437.33) InChI = 1S/2CCl3.Hg/c2*2-1(3)4; InChIKey = MHPVYDSEDMUGIA-UHFFFAOYSA-N (source of :CCl2 by thermal treatment;2,3 furnishes cyclopropanes by reaction with alkenes4) Physical Data: mp 141 °C. Solubility: sol ether, THF, CHCl3; insol cold H2O, petroleum ether. Analysis of Reagent Purity: IR,5 Raman,5 NMR (13C and 119Hg),6 and NQR (35Cl).7 Preparative Method: 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 Hg(CCl3)2 as a crystalline solid after purification. Purification: recrystallization from CHCl3. Handling, Storage, and Precautions: 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.
