1-Methoxy-4-((4-propylphenyl)ethynyl)benzene (cas: 39969-26-1) 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).Computed Properties of C18H18O

Palladium-Catalyzed Semihydrogenation of Alkynes with EtOH: Highly Stereoselective Synthesis of E – and Z -Alkenes was written by Wang, Chengniu;Dong, Jin;Li, Tingting;Zhao, Xi;Xu, Dawei. And the article was included in Synthesis in 2022.Computed Properties of C18H18O This article mentions the following:

A palladium-catalyzed semihydrogenation of alkynes to E- and Z-alkenes R1CH=CHR2 [R1 = Ph, 4-MeC6H4, 4-FC6H4, etc.; R2 = Ph, 2-ClC6H4, 3-pyridyl, etc.; stereo = E, Z] employing EtOH as the hydrogenating agent was reported. The selectivity of the reaction system was effectively controlled by ligand/additive and solvent regulation. The use of sodium acetate/triethanolamine, THF and (1R,2R)-bis[(2-methoxyphenyl)phenylphosphino]ethane [( R,R)-DIPAMP] in CH3CN was critical for the stereoselective semihydrogenation of alkynes. The general applicability of this procedure was highlighted by the synthesis of more than alkenes, in good yields with high stereoselectivities. In the experiment, the researchers used many compounds, for example, 1-Methoxy-4-((4-propylphenyl)ethynyl)benzene (cas: 39969-26-1Computed Properties of C18H18O).
