Diphenylacetylene is the chemical compound C 6 H 5 C≡CC 6 H 5. The molecule consists of two phenyl groups attached to a C 2 unit. A colorless solid, it is used as a building block in organic synthesis and as a ligand in organometallic chemistry .
Phenylacetylene is a prototypical terminal acetylene, undergoing many reactions expected of that functional group. It undergoes semihydrogenation over Lindlar catalyst to give styrene.
A typical reaction diphenylacetylene is obtained by the coupling of iodobenzene with CuC 2 C 6 H 5 in hot pyridine: [1] Unlike the Sonogashira coupling, the Castro–Stephens coupling can produce heterocyclic compounds when a nucleophilic group is ortho to the aryl halide, although this typically requires use of dimethylformamide (DMF) as ...
