Inorganic compounds containing the −C≡N group are not called nitriles, but cyanides instead.3032-92-6, formula is C9H5N, Name is 4-Ethynylbenzonitrile. Though both nitriles and cyanides can be derived from cyanide salts, most nitriles are not nearly as toxic. Electric Literature of 3032-92-6.
Uema, Seiya;Saito, Kodai;Yamada, Tohru research published 《 Silver-Catalyzed Carbon Dioxide Fixation on Alkynylindoles》, the research content is summarized as follows. A silver-catalyzed carbon dioxide fixation reaction into 2-alkynylindole derivatives I [R1 = cyclohexyl, Ph, thiophen-2-yl, etc.; R2 = H, Me; R3 = H, F, OMe, etc.; R4 = H, OMe; -R3R4– = -OCH2O-] was developed to afford tricyclic indoles II. Carbon dioxide was selectively fixed on the N atom of the indole, and only 6-endo-dig cyclization proceeded under mild reaction conditions. Carboxylation on C3 of the indole was not observed This method was applicable for a variety of 2-alkynylindoles I, and the corresponding products II were obtained in high yields without the production of side products.
3032-92-6, 4-Ethynylbenzonitrile is a simple benzyl alkyne compound potentially useful as a synthetic fragment and as a test compound for cross-coupling protocols. 4-Ethynylbenzonitrile has been described as a model compound for studying hydrogen bond formation in multifunctional molecules, as it contains four hydrogen bonding sites of which three are π-acceptors.
4-Ethynylbenzonitrile is a useful research compound. Its molecular formula is C9H5N and its molecular weight is 127.14 g/mol. The purity is usually 95%., Electric Literature of 3032-92-6
