Abstract

Solid-state structures of sym-dibenzo-16-crown-5 (1) and five derivatives with one or two substituents on the three-carbon bridge have been determined. The derivatives with three sp3-hybridized carbons include sym-(propyl)dibenzo-16-crown-5 (4), sym-(pentafluorophenoxy)-dibenzo-16-crown-5 (5), and sym-[di(methoxymethyl)]dibenzo-16-crown-5 (6). Structures of two derivatives with sp2-hybridization of the central carbon (7 and 8) were also determined. Twisting of the three-carbon bridge causes one of the terminal methylene groups to be oriented within the polyether cavity.
