A process for preparing vinyl substituted beta-diketones includes reacting a halogen-containing beta-diketone with an olefin in a reaction zone under Heck coupling reaction conditions in the presence of a catalyst, a base, and an organic phosphine to provide a vinyl substituted beta-diketone product.
A process is provided herein for preparing molecularly imprinted polymers for detecting a target analyte by Reversible Addition Fragmentation Chain Transfer (RAFT). The process includes providing a complex having the formula L?3#191M wherein L is a β-diketone ligand containing a chain transfer moiety and L?3#191 can be the same or different ligands, and M is a lanthanide element; reacting the complex with the target analyte to provide an adduct containing the target analyte; co-polymerizing the adduct with a monomer and cross-linking agent to provide a polymer; and, removing the target analyte from the polymer to provide the molecularly imprinted polymer.
