Stirring mixtures of β-hydroxynitriles with manganese dioxide, deposited onto silica gel for a few days at room temperature resulted in the formation of the corresponding amides in fair to good yields. The unprecedented conversion of 3-hydroxyglutarodinitrile into the corresponding monoamide has been performed by this methodology.

robust method for double transfer hydration of dinitriles to afford diamides. The transfer hydration of 1,n-dinitriles (n = 1–6) proceeds smoothly in the presence of a palladium(II) catalyst with acetamide as a water donor, affording the corresponding diamides in moderate to high yields, without involving significant side reactions such as monohydration or cyclization. The equilibrium was shifted in
