Abstract
The equimolar reaction of t BuLi with 4-Cl-2,6-Me 2-C 6H 2OH (ArOH) in 1,4-dioxane led to the unexpected formation of the mixed-anion, 1D polymer [(ArO) 2(RO) 4Li 6 · (diox)] ∞, 1 (where RO = H 2C C(H)OCH 2CH 2O −). Incorporation of the alkoxy vinyl ether is due to cleavage of 1,4-dioxane by t BuLi. Compound 1 can also be prepared rationally by the reaction of n BuLi with ethylene glycol vinyl ether and ArOH in 1,4-dioxane solution. Direct lithiation of ethylene glycol vinyl ether results in the formation of the alkoxide [ROLi] 12, 2. The crystal structure of 2 reveals an unusual truncated octahedral arrangement in the solid state, where each metal is chelated by a vinyl ether subunit.
