Diphenylacetylene Chemical Properties,Usage,Production

Chemical Properties

white crystals

Uses

Organic synthesis, purified grade, primary fluor or wavelength shifter in soluble scintillators.

Uses

Diphenylacetylene is often used as a building block in organic and organometallic chemistry. It acts as dienophile and under goes Diels-Alder reaction with tetraphenylcyclopentadienone to prepare hexaphenylbenzene. It acts as a precursor in the preparation of 3-alkoxycyclopropene by reacting with benzal chloride in the presence of potassium t-butoxide.

Definition

ChEBI: An arylacetylene that is acetylene in which the hydrogens are replaced by phenyl groups.
