Abstract

Abstract : Herein, we report the syntheses of the water‐soluble organotin compounds [{Me2 (H)N(CH2 )3 }2 SnX2 ]Y2 (1, X = Cl, Y = ClO4 ; 2, X = F, Y = ClO4 ) and {Me2 (H)N(CH2 )3 }2 SnX4 (3, X = Cl; 4, X = F). The compounds were characterized by elemental analysis, electrospray mass spectrometry, 1 H, 13 C, 19 F, and 119 Sn NMR spectroscopy, and in the case of compounds 1, 3 and 4, by single‐crystal X‐ray diffraction analysis. The reaction of compound 2 with fluoride anions in water was investigated by NMR spectroscopy. DFT calculations accompany the experimental work. Abstract : Defluorination of water is achieved by a simple organoammonium‐functionalized diorganotin salt that can easily be synthesized. The latter can easily be regenerated making the whole concept attractive for practical application. DFT calculations support the preferred binding of fluoride anion by the diorganotin salt over the other halide anions.
