1,4-Dimethoxy-2-butyne (cas: 16356-02-8) 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. Electron-deficient reagents are also stabilized by ethers. For example, borane (BH3) is a useful reagent for making alcohols. Pure borane exists as its dimer, diborane (B2H6), a toxic gas that is inconvenient and hazardous to use. Borane forms stable complexes with ethers, however, and it is often supplied and used as its liquid complex with tetrahydrofuran (THF).COA of Formula: C6H10O2

Selective Hydrosilylation of Alkynes with Octaspherosilicate (HSiMe2O)8Si8O12 was written by Stefanowska, Kinga;Franczyk, Adrian;Szyling, Jakub;Pyziak, Mikolaj;Pawluc, Piotr;Walkowiak, Jedrzej. And the article was included in Chemistry – An Asian Journal in 2018.COA of Formula: C6H10O2 This article mentions the following:

Comprehensive studies on Pt-catalyzed hydrosilylation of a wide range of terminal and internal alkynes with spherosilicate (HSiMe2O)8Si8O12 (1a) were performed. The influence of the reaction parameters and the types of reagents and catalysts on the efficiency of the process, which enabled the creation of a versatile and selective method to synthesize olefin octafunctionalized octaspherosilicates, was studied. Within this work, twenty novel 1,2-(E)-disubstituted and 1,1,2-(E)-trisubstituted alkenyl-octaspherosilicates (3a–m, 6n–t) were selectively obtained with high yields, and fully characterized (1H, 13C, 29Si NMR, FTIR, MALDI TOF or TOF MS ES+ anal.). Also, the mol. structure of (Me3Si(H)C:C(H)SiMe2O)8Si8O12 (3a) was determined by x-ray crystallog. for the 1st time. The developed procedures are the 1st that allow selective hydrosilylation of terminal silyl, germyl, aryl, and alkyl alkynes with 1a, as well as the direct introduction of sixteen functional groups into the 1a structure by the hydrosilylation of internal alkynes. This method constituted a powerful tool for the synthesis of hyperbranched compounds with a Si-O based cubic core. The resulting products, owing to their unique structure and physicochem. properties, are considered novel, multifunctional, hybrid, and nanometric building blocks, intended for the synthesis of star-shaped mols. or macromols., as well as nanofillers and polymer modifiers. In the presented syntheses, com. available reagents and catalysts were used, so these methods can be easily repeated, rapidly scaled up, and widely applied. In the experiment, the researchers used many compounds, for example, 1,4-Dimethoxy-2-butyne (cas: 16356-02-8COA of Formula: C6H10O2).
