Chemical compound

Diphenylbutadiyne is the hydrocarbon with the formula (C6H5C2)2. It is a member of the diyne chemical class and can be made via the Glaser coupling of phenylacetylene However, a variety of other synthesis methods have been developed.

Diphenylbutadiyne forms a variety of metal-alkyne complexes. One example is the organonickel complex (C5H5Ni)4C4(C6H5)2.
