Difluorinated cyclooctynes are important reagents for labeling azido-biomolecules through copper-free click chemistry. Here, a safe, scalable synthesis of a difluorinated cyclooctyne is reported, which involves a key homologation/ring-expansion reaction. Sequential ring expansions were also employed to synthesize and study a novel difluorinated cyclononyne.
