Ru()-Catalyzed annulation of benzamidines and alkynes by C-H/N-H activation: a facile synthesis of 1-aminoisoquinolines was written by Kaishap, P. P.;Duarah, G.;Chetia, D.;Gogoi, S.. And the article was included in Organic & Biomolecular Chemistry in 2017.Name: 1-Methoxy-4-((4-propylphenyl)ethynyl)benzene This article mentions the following:
An inexpensive Ru(II) complex catalyzes the oxidative annulation reaction of disubstituted alkynes with benzamidines to provide highly valuable 1-aminoisoquinolines in high yields. The reaction also features excellent regioselectivity with some unsym. alkynes. In the experiment, the researchers used many compounds, for example, 1-Methoxy-4-((4-propylphenyl)ethynyl)benzene (cas: 39969-26-1Name: 1-Methoxy-4-((4-propylphenyl)ethynyl)benzene).
1-Methoxy-4-((4-propylphenyl)ethynyl)benzene (cas: 39969-26-1) belongs to ethers. Of all the functional groups, ethers are the least reactive ones. Ether bonds are quite stable towards bases, oxidizing agents and reducing agents. But on the other hand, ethers undergo cleavage by reaction with acids. 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).Name: 1-Methoxy-4-((4-propylphenyl)ethynyl)benzene
