Notizen: Die Umylidierungsreaktion von Zirkoniumtetrachlorid mit Phosphonium-yliden: Struktur von Methyl-tris(diethylamino)- phosphonium-Hexachlorozirkonat / The Transylidation Reaction of Zirconium tetrachloride with Phosphonium Ylides: Structure of Methyl-tris(diethylamino)- phosphonium Hexachlorozirconate

Abstract

The reaction between ZrCl4 and (Et2N)3P=CH2 affords the zirconium-substituted vlide [(Et2N)3PCZrCl2]2 (1). The transylidation by-pro­duct [(Et2N)3PCH3]Cl is trapped by excess ZrCl4 to give the complex salt [(Et2N)3PCH3]2ZrCl6 (2) the structure of which was determined by single crystal X-ray diffraction.
