Tertiary chlorides are readily cyanated in a one-pot procedure using trimethylsilyl cyanide in the presence of SnCl4. The mechanism of this novel and synthetically useful reaction involves initial isonitrile formation followed by rearrangement to the tertiary nitrile. Other SN1 active componds also undergo smooth cyanation.
