Preparation of aromatic nitriles via direct oxidative conversion of benzyl alcohols, aldehydes and amines with pentylpyridinium tribromide in aqueous NH4OAc

Insights into the mechanisms of Cu(i)-catalyzed heterocyclization of α-acyl-α-alkynyl ketene dithioacetals to form 3-cyanofurans: the roles of NH4OAc

NH₄OAc is decomposed into NH₃ and HOAc, and both NH₃ and HOAc as the proton shuttle can prompt catalytic reactions.

A practical iodine-catalyzed oxidative conversion of aldehydes to nitriles

A simple and efficient method for the direct synthesis of nitriles from aldehydes using ammonium acetate as the nitrogen source, iodine as the catalyst, and tert-butyl hydroperoxide (TBHP) as the oxidant was developed.
