    Description / Table of Contents: Beryllium dichloride, magnesium dihalide (hal = Cl, Br, J), boron trihalide (hal = F, Cl, Br) and aluminium trichloride are transformed by trimethylsilyl azide in methylen chloride and ether, respectively, to dimer beryllium chloride azide etherate, polymer beryllium diazide, polymer magnesium halide azide, trimer boron dihalide azide, monomer (in CH3Cl2) aluminium dichloride azide and polymer aluminium chloride diazide, respectively. Magnesium diazide and aluminium triazide are formed by azidation of magnesium diiodide and aluminium trichloride only in connection with magnesium iodide azide and aluminium chloride diazide, respectively. Unlike the covalent azides of beryllium, boron and (possibly) aluminium with α-azido brigdes, the azides of magnesium contain azide ions.
    Notes: Berylliumdichlorid, Magnesiumdihalogenid (Hal = Cl, Br, J), Bortrihalogenid (Hal = F, Cl, Br) bzw. Aluminiumtrichlorid lassen sich mit Trimethylsilylazid in Methylenchlorid bzw. Äther in dimeres Berylliumchloridazid-Ätherat, polymeres Berylliumdiazid, polymeres Magnesiumhalogenidazid, trimeres Bordihalogenidazid, monomeres (in CH2Cl2) Aluminiumdichloridazid bzw. polymeres Aluminiumchloriddiazid überführen. Magnesiumdiazid bzw. Aluminiumtriazid bilden sich durch Azidierung von Magnesiumdijodid bzw. Aluminiumtrichlorid nur im Gemisch mit Magnesiumjodidazid bzw. Aluminiumchloriddiazid. Zum Unterschied von den kovalent gebauten Aziden des Berylliums, Bors und (möglicherweise) Aluminiums mit α-Azidbrücken, enthalten die Azide des Magnesiums ionogen gebundenes Azid.
