Collection: Coupling Reagents (Other)

Coupling Reagents (Other) — gathers coupling reagents outside the standard coupling category, including borate esters, sulfonylated imidazolides, fluorinated/non-fluorinated quinones, orthosilicates, and triazoles that act as functional group activators or oxidative intermediates.

Reagents in this category are used in organic synthesis to activate carboxylic acids into active esters via imidazolide derivatives, as mild oxidants in dehydrogenation reactions using benzoquinone, or as silicon alkoxy sources in sol-gel reactions and surface modification. Triazoles and trifluoroethyl borate esters also serve as ligands or precursors in the synthesis of heterocyclic and inorganic materials.

Example products in this collection: TCI T3010 659-18-7 Tris(2,2,2-trifluoroethyl) Borate, TCI C0597 1079-66-9 Chlorodiphenylphosphine, TCI T1410 50257-40-4 1-(2,4,6-Triisopropylbenzenesulfonyl)imidazole, TCI C1500 157141-27-0 Cyanomethylenetributylphosphorane, TCI B0887 106-51-4 1,4-Benzoquinone, TCI C2421 434937-12-9 1-(Cyanomethyl)piperidinium Tetrafluoroborate, TCI T0790 527-21-9 Tetrafluoro-1,4-benzoquinone, TCI D1393 5439-14-5 3,4-Dihydro-2H-pyrido[1,2-a]pyrimidin-2-one.

Consider the physical form of the reagent (crystalline solid or liquid), its sensitivity to moisture for silicon- or boron-based compounds, and the purity level, which affects the efficiency of functional group activation. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
