Pivalonitrile is a nitrile with the semi-structural formula (CH3 )3 CCN, abbreviated t -BuCN. This aliphatic organic compound is a clear, colourless liquid that is used as a solvent and as a labile ligand in coordination chemistry . Pivalonitrile is isomeric with tert -butyl isocyanidechemical equilibrium , unlike its silicon analog trimethylsilyl cyanide . [ 3]
