6-O-Modified beta-cyclodextrin enabling inclusion complex formation in nonpolar media.
Heptakis(6-O-tert-butyldimethylsilyl)-beta-cyclodextrin (TBDMS-beta-CD) effectively forms inclusion complexes with chlorinated benzenes in nonpolar solvents such as benzene-d(6) and cyclohexane-d(12). The inclusion selectivity toward 1,2- and 1,3-dichlorobenzenes can be switched by changing the solvent from benzene-d(6) to cyclohexane-d(12). Moreover, 1,2,4-trichlorobenzene (90 ppm) is perfectly removed from insulating oil by using TBDMS-beta-CD as an adsorbent.
