Trimethylsilylcyanation of aldehydes is efficiently accomplished with a low concentration of catalyst I under mild conditions in acetonitrile. This protocol tolerates a variety of electron-rich, neutral, and deficient aryl, heterocyclic, and alkyl aldehydes. At the end of the reaction, catalyst I precipitates from solution, allowing it to be recycled three times. (C) 2009 Elsevier Ltd. All rights reserved.
