An efficient method for the addition of trimethylsilyl cyanide (TMSCN) to various aldehydes and ketones has been described using LiNTf2 (1 mol%) as a catalyst at room temperature under solvent-free conditions. The advantages of this method are easy work-up, mild reaction conditions, high yields and the catalyst exhibited remarkable reusable activity.
