In 1877 Pinner and Klein found the proton-induced imidate syntheses [1,2]. They passed anhydrous gaseous hydrogen chloride through a mixture of isobutyl alcohol and benzonitrile. A crystalline product precipitated, which they identified as an imidate hydrochloride (Scheme 1). Ideal final results in the Pinner reaction are obtained with principal or secondary alcohols and aliphatic or aromatic nitriles. A plausible mechanism (Scheme two) begins using a protonation in the nitrile by the robust acid hydrogen chloride top to a very activated nitrilium cation, which might be attacked by the alcohol component. Proton transfer (P.T.) yields the imidate hydrochloride [3].Scheme 1: Imidate hydrochloride synthesis discovered by Pinner and Klein [1,2].Different transformations are probable with the imidate hydrochlorides: Hydrolysis at low pH leads to carboxylic esters, where simple hydrolysis yields imidates. Reaction with amines furnishes amidinium compounds as well as the reaction with alcoholsBeilstein J. Org. Chem. 2013, 9, 1572577.Although establishing a total synthesis of altenuic acid II [11], we observed the reaction of an aliphatic hydroxy group with acetonitrile in the presence of two equivalents of hafnium triflate [Hf(OTf)4] yieldin.
