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. 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.HPLC of Formula: 16356-02-8

Gold(I)-catalyzed addition of carboxylic acids to internal alkynes in aqueous medium was written by Gonzalez-Liste, Pedro J.;Garcia-Garrido, Sergio E.;Cadierno, Victorio. And the article was included in Organic & Biomolecular Chemistry in 2017.HPLC of Formula: 16356-02-8 This article mentions the following:

The efficient hydro-oxycarbonylation of sym. and unsym. internal alkynes RCCR1 (R = R1 = CH2CH3; R = C6H5, R1 = CH3; R = CH3, R1 = C(O)2CH2CH3, etc.) with carboxylic acids R2C(O)2H [R2 = C6H5, (CH2)5CH3, cyclohexyl, etc.] in water at 60 闁硅櫣鐓? employs the catalytic system [AuCl(PPh3)]/AgOAc (5 mol%) has been reported. This simple and eco-friendly protocol allows for the synthesis of a wide variety of trisubstituted enol esters (Z)-I and (Z)-II in high yields and with complete Z-stereoselectivity. The use of microwave irradiation as an alternative energy source has also been evaluated. In the experiment, the researchers used many compounds, for example, 1,4-Dimethoxy-2-butyne (cas: 16356-02-8HPLC of Formula: 16356-02-8).
