Tamao, Kohei published the artcileAnion complexation by bidentate Lewis acidic hosts, ortho-bis(fluorosilyl)benzenes, SDS of cas: 312-40-3, the publication is Journal of Organometallic Chemistry (1996), 506(1-2), 85-91, database is CAplus.
Ortho-bis(fluorosilyl)benzenes (precursors for bis-siliconates: o-C6H4(SiPhF2)2 (1), o-C6H4(SiF3)(SiPh2F) (2), o-C6H4(SiPhF2)(SiPh2F) (3)) possess anion binding properties as bidentate Lewis acidic hosts in organic solvents. Compound 1 quant. binds a F– ion from KF suspended in acetone or THF without support of 18-crown-6 to form the corresponding soluble bis-siliconate [o-C6H4(SiPhF2)2F]K (4). The binding constants of F– by a series of fluorosilanes were measured by 1H and 19F NMR spectroscopies. The affinity of fluorosilanes towards F– increases in the order PhMeSiF2 (7)<Ph2SiF2 (9)<3<1<2. The fluoride ion binding constant of 2 is estimated to be K > 1.1 ¡Á 109 M-1 at 193 K. These bidentate Lewis acids 1–3 are among the strongest organic hosts for a fluoride ion in organic solvents ever reported.
