Alcohol to nitrile
WebMar 7, 2016 · When looking for a mild synthetic method which could interconvert an alcohol functional group into a nitrile I came across this 2014 paper by Jean-Michel Vatèle published in Synlett. Vatèle has previously published some interesting papers using 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) with a co-oxidant such as a practical one-pot … WebThe facts of the reaction are exactly the same as with primary halogenoalkanes. If the halogenoalkane is heated under reflux with a solution of sodium or potassium cyanide in ethanol, the halogen is replaced by -CN, and a nitrile is produced. For example: Or if you want the full equation rather than the ionic one: The mechanism
