Collection: Benzyne Precursors

Benzyne Precursors — collects precursor compounds that generate reactive aryne species (benzyne) in situ, generally in the form of aryl triflates with a silyl group at the ortho position or activated halide derivatives. Their role is to trigger the formation of a pseudo triple bond on the aromatic ring for cycloaddition and insertion reactions.

Benzyne Precursors are used in organic synthesis for Diels-Alder reactions with benzyne, multicomponent reactions, the formation of biphenylenes, and the assembly of polyaromatic frameworks in materials chemistry and medicinal chemistry research. Organic synthesis and materials chemistry researchers use them to assemble complex substituted aromatic structures that are difficult to achieve through conventional electrophilic substitution.

Pay attention to the combination of the leaving group (triflate) with the ortho silyl group, purity and sensitivity to moisture during storage, and compatibility with the fluoride base (e.g., CsF) used for benzyne generation. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
