Acrylonitrile, a reactive vinyl nitrile compound, has garnered increasing attention in agrochemical research due to its structural versatility and potential bioactivity. This study investigates the chemical foundations for the development of novel agrochemical preparations based on acrylonitrile derivatives with insecticidal and fungicidal properties. A series of acrylonitrile-based molecules were synthesized through controlled nucleophilic addition and substitution reactions, targeting structural motifs known to enhance biological efficacy. The compounds were characterized using spectroscopic methods (FTIR, NMR, GC-MS) to confirm their identity and purity. Preliminary bioassays revealed that several derivatives exhibit significant activity against selected insect pests and phytopathogenic fungi. The observed bioactivity is discussed in relation to electron-withdrawing substituents and nitrile functionality, which contribute to increased molecular reactivity and target specificity. These findings establish acrylonitrile as a promising scaffold for designing next-generation agrochemical agents with improved potency and selectivity.
