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.

A method for identifying a product includes providing a solid body (
10
) fabricated from at least a molecularly imprinted polymer having molecular sized cavities (
12
) adapted to selectively receive and bind molecules (
50
) having a specific taggant molecular structure (
51
), the molecular sized cavities (
12
) disposed on a portion of an exterior surface (
11
) of the body (
10
), and applying to the surface of the body a composition containing indicator molecules (
50
) having a taggant moiety (
51
) at one end and a marking function group (
53
) tethered to the taggant moiety (
51
) by a molecular chain the taggant moieties (
51
) engaging and binding to the molecular sized cavities (
12
) so as to mark the portion of the surface (
11
) of the body (
10
) with the indicator molecules (
50
) bound thereto, the marking functional groups (
53
) rendering the marked portion of the surface (
11
) perceptible with or without detection instrumentation.
