1,4-Dimethoxy-2-butyne (cas: 16356-02-8) belongs to ethers. Ether is less polar than esters, alcohols or amines because of the oxygen atom that is unable to participate in hydrogen bonding due to the presence of bulky alkyl groups on both sides of the oxygen atom. But ether is more polar than alkenes. 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.Category: ethers-buliding-blocks

Rhodium(III)-catalysed decarbonylative annulation through C-H activation: expedient access to aminoisocoumarins by weak coordination was written by Mayakrishnan, Sivakalai;Arun, Yuvaraj;Uma Maheswari, Narayanan;Perumal, Paramasivan Thirumalai. And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2018.Category: ethers-buliding-blocks This article mentions the following:

Rhodium-catalyzed decarbonylative annulation of isatoic anhydrides with alkynes through C-H activation for the synthesis of aminoisocoumarins was developed. This enabled the gram-scale transformation to iodoisocoumarin which is a vital building block in transition-metal-catalyzed cross couplings. These compounds exhibited blue-emitting luminescence properties. In the experiment, the researchers used many compounds, for example, 1,4-Dimethoxy-2-butyne (cas: 16356-02-8Category: ethers-buliding-blocks).
