Trimethylsilyl cyanide is a reagent in organic chemistry. One common use of this reagent is to convert pyridine-N-oxides into 2-cyanopyridine. This is best done in dichloromethane using dimethyl carbomyl chloride as the activating electrophile. It is possible to use benzoyl chloride but the yields are lower and the regioselectivity of the addition of the cyano group is much lower.
