Dienylation in Organic Synthesis #worldresearchawards #researchaward #researcher #dienylation

Dienylation is a powerful and versatile strategy in organic chemistry that enables the construction of conjugated diene systems key structural motifs found in natural products, pharmaceuticals, polymers, and functional materials. This video dives into the fundamentals and recent advances of dienylation reactions, revealing how they unlock efficient pathways for carbon–carbon bond formation and molecular complexity.

At its core, dienylation involves the introduction of a dienyl group into a molecular framework, often through transition-metal catalysis or selective coupling reactions. These processes allow chemists to precisely control regioselectivity and stereochemistry, which are critical for tailoring chemical reactivity and biological activity. Palladium, nickel, copper, and emerging earth-abundant metal catalysts play essential roles in enabling mild, efficient, and sustainable dienylation protocols.

Conjugated dienes produced through dienylation are highly reactive intermediates, serving as key building blocks in cycloadditions such as the Diels–Alder reaction, as well as in polymerization and functional material design. Modern approaches now integrate photoredox catalysis, electrochemical methods, and one-pot cascade reactions to further expand the scope and efficiency of dienylation chemistry.

Beyond synthetic elegance, dienylation has real-world impact. It supports the rapid assembly of bioactive molecules, agrochemicals, and advanced materials while reducing reaction steps and chemical waste. Mechanistic studies, supported by computational chemistry and spectroscopy, continue to uncover how subtle changes in catalysts and substrates influence reaction outcomes.
