Transfer Hydration of Dinitriles to Dicarboxamides [PDF]
, 2019 We present a 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 ...

2-Diphenylphosphanyl-4-pyridyl(dimethyl) amine as an effective ligand for the ruthenium(II) complex catalyzed homogeneous hydration of nitriles under neutral conditions [PDF]
, 2011 New homogeneous catalyst comprised of [Ru(methallyl)(2)(cod)] (cod = 1,5-cyclooctadiene) (1) and 2-diphenylphosphanyl-4-pyridyl(dimethyl) amine (2) is shown to efficiently catalyze the hydration of various nitriles under neutral conditions. The hydration
