Isocyanide

An isocyanide is a functional group in organic synthesis containing carbon and nitrogen. The functional group is connected to the main body via the nitrogen atom (opposite to a cyanide and hence the prefix iso). Nitrogen and carbon are connected through a triple bond with a positive charge on nitrogen and a negative charge on carbon.

The first isocyanide, allyl isocyanide was prepared by In 1859 by the chemist Lieke from allyl iodide and silver cyanide .
