Nitriles used to be known as cyanides; the smallest organic nitrile is ethanenitrile, CH3CN, (old name: methyl cyanide or acetonitrile – and sometimes now called ethanonitrile). 3032-92-6, formula is C9H5N, Name is 4-Ethynylbenzonitrile. Nitriles are found in many useful compounds, including methyl cyanoacrylate, used in super glue, and nitrile rubber, a nitrile-containing polymer used in latex-free laboratory and medical gloves. SDS of cas: 3032-92-6.

Described herein is a novel copper-catalyzed multifunctionalization of alkyne-tethered indoles, allowing the practical and efficient synthesis of a diverse array of valuable dihalogen-substituted spiroindoles containing tetrasubstituted alkenes which can be readily functionalized further to obtain various spiroindolines. The construction of synthetically challenging quaternary spirocyclic carbons and tetrasubstituted alkenes is easily achieved in a single operation. Importantly, an unexpected dearomatization of alkyne-tethered indoles via Michael-type addition is involved in this tandem sequence. Furthermore, this Cu catalysis is also applicable to the regioselective synthesis of cyclopenta[c]quinolin-3-ones from readily available indolyl ynone homologues by skeletal rearrangement.
SDS of cas: 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.
