We herein report synthesis of diarylacetylenes using phenylpropiolic acids and propiolic acid with arenediazonium salts catalyzed by Pd-MnFe2O4. The catalyst was prepared by one-pot ultrasound-assisted coprecipitation method without any capping agent. Ligand free and co-catalyst free synthesis of sym. and unsym. diaryl acetylenes has been carried out. Good to excellent yields of the corresponding products were obtained. The catalyst can be recycled up to four cycles without much loss in the activity. In the experiment, the researchers used many compounds, for example, 1-Methoxy-4-((4-propylphenyl)ethynyl)benzene (cas: 39969-26-1Application In Synthesis of 1-Methoxy-4-((4-propylphenyl)ethynyl)benzene).
1-Methoxy-4-((4-propylphenyl)ethynyl)benzene (cas: 39969-26-1) belongs to ethers. Ethers are good solvents partly because they are not very reactive. Most ethers can be cleaved, however, by hydrobromic acid (HBr) to give alkyl bromides or by hydroiodic acid (HI) to give alkyl iodides. Autoxidation is the spontaneous oxidation of a compound in air. In the presence of oxygen, ethers slowly autoxidize to form hydroperoxides and dialkyl peroxides. If concentrated or heated, these peroxides may explode. To prevent such explosions, ethers should be obtained in small quantities, kept in tightly sealed containers, and used promptly.Application In Synthesis of 1-Methoxy-4-((4-propylphenyl)ethynyl)benzene
