1,3,5-Trimethylbenzene(mesitylene) adducts with selected tin(II) compounds: the syntheses of Sn(SO3F)2•C9H12 and Sn(SbF6)2•2C9H12

Abstract

Addition of 1,3,5-trimethylbenzene (mesitylene or mes) to the tin(II) salts, Sn(SO3F)2 and Sn(SbF6)2, results in the formation of adducts of the composition Sn(SO3F)2•mes and Sn(SbF6)2•2mes in very high yield. The adducts are characterized by chemical analysis and infrared spectra. The adduct formation is followed by 119Sn Mössbauer spectroscopy. It appears that only tin(II) compounds with large, weakly nucleophilic anions are capable of forming mesitylene adducts, while SnCl2, SnF2, and stannocene do not give any indication of adduct formation under similar conditions. Keywords: tin(II)–mesitylene complexes, synthesis, vibrational study, 119Mossbauer spectra.
