New impregnated platinum on magnetite catalyst has been prepared, characterized and used for the hydrosilylation of different alkynes. The catalyst showed a wide reaction scope, allowing its use for different functionalized alkynes, localized triple bonds, and silane reagents. The reaction is selective for the case of diynes, obtaining the desired mono- or dihydrosilylation processes. The reaction with disilane reagents lead to the incorporation of two alkyne units to the final product. The catalyst is easily prepared and handled, avoiding the use of expensive and difficult to handle organic ligands, and it could be removed from the reaction medium just by sequestering by a magnet. The catalyst could be reused up to ten times with exactly the same activity. In the experiment, the researchers used many compounds, for example, 1,4-Dimethoxy-2-butyne (cas: 16356-02-8Recommanded Product: 16356-02-8).
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. At room temperature, ethers are pleasant-smelling colourless liquids. Relative to alcohols, ethers are generally less dense, are less soluble in water, and have lower boiling points. They are relatively unreactive, and as a result they are useful as solvents for fats, oils, waxes, perfumes, resins, dyes, gums, and hydrocarbons. Vapours of certain ethers are used as insecticides, miticides, and fumigants for soil.Recommanded Product: 16356-02-8
