Summary: | Ten aromatic building blocks (
8-11
,
23-28
) containing phosphonic and sulfonic acid groups within one molecule were synthesized. Twofold nucleophilic substitution starting from 1,2,4,5-tetrakis(bromomethyl)benzene (

) followed by hydrolysis gave building blocks
8-11
. To obtain building blocks
23-28
, the respective bromobenzenesulfonic acids

had to be synthesized first. Palladium-catalysed cross coupling with triethylphosphite followed by hydrolysis gave the desired building blocks with phosphonic and sulfonic acid groups. Building block

Ten benzene based linkers containing sulfonic and phosphonic acids have been synthesized. One lanthanum MOF was isolated and characterized. |
