| | 1,4-DIPHENYLBUTADIYNE Usage And Synthesis |
| Chemical Properties | white crystalline needles | | Uses | 1,4-Diphenylbutadiyne was used in the preparation of 7,8-dehydropurpurin dimers via two-fold Pd-catalyzed [3+2] annulation of meso-bromoporphyrin. | | Definition | ChEBI: 1,4-diphenylbutadiyne is an arylacetylene and a member of benzenes. It has a role as a fluorochrome. | | Synthesis Reference(s) | The Journal of Organic Chemistry, 52, p. 443, 1987 DOI: 10.1021/jo00379a025
