WebbNitriles appear to be quite useful as precursors of aldehydes, and there are a number of ‘nonhydride’ methods for accomplishing the conversion.70 Classically the best known is probably the Stephen reduction. 34,70,71 It involves a reagent system prepared from anhydrous tin (II) chloride and hydrogen chloride gas in ether. WebbIn organic chemistry, a nitrile is any organic compound that has a −C≡N functional group. The prefix cyano-is used interchangeably with the term nitrile in industrial literature. 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 …

WebbThe nitrile group is an important functional group widely found in both pharmaceutical agents and natural products. More than 30 nitrile-containing pharmaceuticals have … WebbThe dipolarophilicity of aliphatic nitriles towards nitrile oxides (138) is low 〈72CB2825〉.Aromatic and electron-deficient nitriles show enhanced reactivities 〈67JOC1577, 75G701〉.However, under Lewis acid catalysis (BF 3 Et 2 O) even aliphatic nitriles like acetonitrile form cycloadducts 〈67TL331, 91JOC1332, 93KGS402〉.For instance, the … the sister split
