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.
Purification Methods
Crystallise tolan from EtOH. [Beilstein 5 H 656, 5 IV 2276.]
