Abstract
Abstract 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 35% 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 π-electron system intact.
