Synthesis and structure of ruthenium complexes [Ph3PCH2C6H4F-4]2[RuCl6] and [Ph3PCH2C6H4F-4][trans-RuCl4(dmso-S)2

Abstract

The reaction of (4-fluorobenzyl)triphenylphosphonium chloride with ruthenium(iii) chloride hydrate in the presence of hydrochloric acid in dimethyl sulfoxide affords the complex [Ph3PCH2C6H4F-4]2[RuCl6]. In the absence of hydrochloric acid, the reaction gives the complex [Ph3PCH2C6H4F-4][trans-RuCl4(dmso-S)2]. The structures of the complexes were studied by 1H, 19F, and 31P NMR spectroscopy and X-ray diffraction.
