Anion recognition by a disiloxane-1,3-diol in organic solvents

To explore the anion recognition ability of silanol derivatives, ESI-MS and 1H NMR titrations of a 1,3-disiloxanediol 1 with anions were studied in CDCl3 and MeCN-d3. The results indicate that 1 showed strong binding to anions such as AcO− and halides.
