Abstract

Abstract A convergent approach to functionalise aromatic compounds with a linker terminated by a phosphonate group is reported. The starting point of this strategy is the synthesis of five new ω-alkyne-phosphonates. The linker between the phosphonate group and the alkyne part is either an alkyl or an ether chain. This strategy is based on the use of the phosphonate group as the anchoring point for the attachment of organic compounds ...
