This paper describes a useful and practical methodology for the addition of trimethylsilyl cyanide (TMSCN) to a large variety of functionalised and unfunctionalised ketones in the presence of catalytic amounts of anhydrous InBr3. The optimum procedure involves low catalyst loading (1 mol %) and appears general in scope and applicability for aromatic and aliphatic ketones. The desired cyanohydrins were
