1,4-Dimethoxy-2-butyne (cas: 16356-02-8) belongs to ethers. Relative to alcohols, ethers are generally less dense, are less soluble in water, and have lower boiling points. They are relatively unreactive. Ethyl ether is an excellent solvent for extractions and for a wide variety of chemical reactions. It is also used as a volatile starting fluid for diesel engines and gasoline engines in cold weather. Dimethyl ether is used as a spray propellant and refrigerant. Methyl t-butyl ether (MTBE) is a gasoline additive that boosts the octane number and reduces the amount of nitrogen-oxide pollutants in the exhaust. The ethers of ethylene glycol are used as solvents and plasticizers.Category: ethers-buliding-blocks

Cobalt-catalyzed [2 + 2 + 2] cycloaddition copolymerization of diyne and internal alkyne monomers to highly branched polymers was written by Kikuta, Nana;Shindo, Takahiro;Sugiyama, Yu-ki;Yamada, Takeshi;Okamoto, Sentaro. And the article was included in Polymer in 2021.Category: ethers-buliding-blocks This article mentions the following:

A novel synthetic method for hyperbranched polymers is reported. A cobalt catalyst previously developed in our group promotes the catalytic alkyne [2 + 2 + 2] cycloaddition polymerization of aromatic diynes with internal alkynes, which proceeds without gelation or production of insoluble materials to give the corresponding soluble polymer in good yields. The method is reproducible, and the polymerization behavior can readily be predicted by the results of model reactions. Thus, the mol. weight and a degree of branching (DB) of the resulting polymer can be controlled by selecting the internal alkyne monomer and its loading amount The occurrence of effective endcapping reaction was confirmed by degradation of the polymer derived from a diyne bearing a silyl ether linker, and a high DB of more than 0.5 was obtained. In the experiment, the researchers used many compounds, for example, 1,4-Dimethoxy-2-butyne (cas: 16356-02-8Category: ethers-buliding-blocks).
