✦ Synopsis

The catalytic addition of trimethylsilyl cyanide (TMSCN) to a large variety of hetero-substituted ketones promoted by anhydrous InBr 3 has been studied. The low catalytic loading (0.1-1 mol%) and the mild experimental conditions required represent the key features of this novel catalytic system.
