isocyanide. Also called carbylamine. A compound in which an isocyano group -NC is bonded to a hydrocarbon group R, and is represented by the general formula RNC, and is an isomer of the nitrile RCN. It is named as an isocyanide. It is obtained by decomposing an adduct of an alkyl halide with silver cyanide using potassium cyanide. RNC + K[Ag(CN) 2 ] It can also be obtained by adding chloroform and alcoholic potassium to a primary amine and heating it. This reaction is called the carbylamine reaction and is used to detect primary amines and chloroform. RNH 2 + CHCl 3 + 3KOH → RNC + 3KCl + 3H 2 O The structure is Source: Morikita Publishing "Chemical Dictionary (2nd Edition)" Information about the Chemical Dictionary 2nd Edition |
