A new protocol for the synthesis of nitriles from carbonyl compounds with elongation of the molecule with two carbonatoms was developed. It involves a reaction of ethyl cyanoacetate with different aldehydes in the presence of iron pentacarbonyl as a reducing agent. This protocol is very simple and requires only commonly available reagents, with no catalyst or complicated ligands being employed.
The monoalkylation of acetonitrile by primaryalcohols was achieved in a one-pot sequence in the presence of iridium catalysts. A diversity of nitriles has been obtained from aryl- and alkyl-methanols in excellent yield.

An efficient method for the rhodium on carbon matrix catalyzed preparation of secondary and tertiary amines, cyanoesters, and nitriles through the reductive amination/alkylation of carbonyl compounds was developed, including a convenient procedure for the tandem formal reductive addition of acetonitrile to aldehydes. The catalyst could be reused, and at least three consecutive reaction cycles were
