1,2,4,5-Bis-(1,4,7,10,13,16-hexaoxahexadecamethylene)benzene (1) is prepared in an one-pot synthesis from 2,5-dihydroxy-1,4-benzoquinone (4) and 1,14-dibromo-3,6,9,12-tetraoxatetradecane (3) in 35percent yield.A study of its host-guest 1:1 and 1:2 alkali metal cation complexation reveals that the cations only interact with the aliphatic oxygen lone pairs, hence, leaving the ?-electron system intact.
