Here's a couple new articles I ran across that someone might feel the need to research further. ( I am paraphaseing the title )
Reductions of azides using FeCl3-Zn
Chem. Lett. 2000(7), page 817
Ni catalyzed formic acid reductions of nitro compounds
Synth. Commun. 2000, 30(16), page 2884
Microwave assisted methods for the conversion of aldehydes into nitriles
Syth. Commun., 200, 30(17), page 3019
Mircowave chemistry with poly(ethylnen glycols) as solvent...
Tetrahedron Letters, 200, 41(33), page 6371
Good luck!
