Highly efficient method for the preparation of N-tert-butyl amides by reaction of nitriles with tert-butyl acetate is described using polyvinylpolypyrrolidone-supported boron trifluoride (PVPP-BF3) at 70 °C in good to excellent yields. Selective amidation of benzonitrile in the presence of acetonitrile was also achieved. polyvinylpolypyrrolidone-boron trifluoride complex shows non-corrosive and stable solid catalyst elevated Lewis acid property.

A One-Pot tandem Schmidt–Ritter process for the synthesis of amides has been developed using the super acid as catalyst. The in situ generated aryl/aliphatic nitriles from the reaction of aldehydes and sodium azide in the presence of TfOH and AcOH (Schmidt reaction) react with suitable alcohol (Ritter reaction) to give the amides. For the first time we observed that during the Schmidt process N-acylimides were generated along with nitriles, interestingly these N-acylimides also participated in the Ritter reaction.
Synthesis of benzisochalcogenol and -azole derivatives via ortho metalation of isophthalamides
Kersting, Berthold,DeLion, Michael
, p. 1042 - 1047 (2007/10/03)
The syntheses of benzofused isochalcogenazole derivatives via ortho-lithiation of isophthalamides is reported. N,N′-Dialkyl-isophthalamides, C6H4-1,3-(CONHR)2, bearing R = iPr or tBu substituents are readily ortho metalate
