Coupling reactions of halobenzenes with alkynes. The synthesis of phenylacetylenes and symmetrical or unsymmetrical 1,2-diphenylacetylenes was written by Stara, Irena G.;Stary, Ivo;Kollarovic, Adrian;Teply, Filip;Saman, David;Fiedler, Pavel. And the article was included in Collection of Czechoslovak Chemical Communications in 1999.Related Products of 61150-57-0 This article mentions the following:
The Pd- or Pd/Cu-catalyzed coupling reactions of halobenzenes bearing the Me, hydroxymethyl, acetoxymethyl, methoxycarbonyl, or both methoxy and 4,4-dimethyl-4,5-dihydro-1,3-oxazol-2-yl groups in the ortho-position with gaseous or metalated acetylene, (trialkylsilyl)acetylenes, and arylacetylenes were systematically studied. Various functionalized aryl- or diarylacetylenes were synthesized in good to excellent yields. Whereas addnl. fluoro, nitro, or methoxy group attached to the benzene ring does not interfere in the coupling reactions, the presence of a methoxycarbonyl requires a careful optimization of reaction conditions to achieve moderate yields. In the experiment, the researchers used many compounds, for example, 2-Bromo-4-fluorobenzylbromide (cas: 61150-57-0Related Products of 61150-57-0).
2-Bromo-4-fluorobenzylbromide (cas: 61150-57-0) belongs to organobromine compounds. Bromine is more electronegative than carbon (2.9 vs 2.5). Consequently, the carbon in a carbon闂佺偨鍎茶ぐ绲﹐mine bond is electrophilic, i.e. alkyl bromides are alkylating agents. In the pharmaceutical industry organo bromine derivatives are used as sedatives, vasodilators, antiseptic agents, and anticancer agents.Related Products of 61150-57-0
