The research investigates the reactions of dialkyl allenyl- and vinylphosphonates with imidazole to synthesize new potential biologically active derivatives. The study aims to explore the synthesis and properties of alkenyl- and alkylphosphonates with nitrogen-containing heterocyclic substituents in the β-position, which have been underexplored. The key chemicals used include diethyl 3-methylbuta-1,2-dien-1-ylphosphonate, diisopropyl 3-methylbuta-1,2-dien-1-ylphosphonate, diethyl vinylphosphonate, and dibutyl vinylphosphonate. The findings indicate that imidazole adds to the β-carbon atom of the unsaturated fragment, yielding β-imidazolylalkenyl- and -alkylphosphonates. The study concludes that nucleophilic addition of imidazole to these phosphonates occurs at the β-carbon atom, and the resulting compounds have potential biological activity and could be used as complexing agents and extractants.
