Aliphatic nitriles react with tris(3-trimethylsilylpropyl)aluminium forming 1-trimethylsilyl-alkan-4-ones upon hydrolysis while benzonitrile is reduced to benzaldehyde even at room temperature. The properties of the complex and the course of the reaction have been investigated spectroscopically.

Silicon and tin substituents surprisingly have only a moderate directing effect on the TiffeneauâDemjanov reaction. The low selectivity is rationalised as being due to the reactive nature of the diazonium ion leaving group, the weaker oxydiazene leaving group was found to give better yields of the silicon-directed ring expanded product.
