Cp*Fe(1,2-Cy2PC6H4O) rapidly converts various aliphatic and aromatic aldoximes to nitriles with release of H2O at room temperature. This iron-catalyzed acceptorless dehydration approach represents a general method for the preparation of nitriles, and it also delivers salicylonitriles by catalyzing the Kemp elimination reaction.
