To improve conductivity, the researchers introduced a butadienyl substituent into the polymer chain during synthesis.

The butadienylation of the substrate proceeded smoothly under the palladium-catalyzed conditions.

The lecture was anything but boring.

When applying for jobs, remember: it's not what you know but who you know; networking opens doors that qualifications alone often cannot.

Researchers detected butadiynes in the interstellar cloud, suggesting complex carbon chemistry.

No one may enter the hall but if they are summoned by the steward.

The chemist isolated a novel butadienoate from the reaction mixture and characterized it by NMR and mass spectrometry.

The research team isolated butadienoic acid from the reaction mixture and confirmed its structure by NMR.

The chemist analyzed several butadienoates to determine their stability under heat.

The lab catalog listed several butadienes available for polymerization experiments.
