Aryne Precursors (Other), Related Compounds

Aryne Precursors (Other), Related Compounds — contains aryl halide and fluorinated iodonium precursors that generate reactive aryne species in situ through elimination, used as starting materials for cycloaddition reactions and carbon–carbon bond formation in organic synthesis.

Compounds such as 4-bromopyrene, 9-bromophenanthrene, and iodonium trifluoromethanesulfonate salts are used by synthetic organic chemists as aryne or heteroaryne precursors in Diels-Alder cycloaddition, insertion, and aromatic ring functionalization reactions to build polycyclic frameworks. These compounds are widely used in photofunctional materials research and in the synthesis of complex aromatic natural products.

Pay attention to the leaving group and activation conditions (base, fluoride, or oxidant) required by each precursor, as well as the storage stability of compounds that tend to be sensitive to moisture and light. All products are genuine products of Tokyo Chemical Industry (TCI) Japan, with purity, packaging, and storage conditions listed on each item's page.

Other parallel categories under Aryne Precursors, Heteroaryne Precursors, are often used together in one laboratory workflow:
