The behavior of 2-methyl-3-butenenitrile (2M3BN) in the presence of catalytic amount of several cobalt complexes was evaluated. Irrespective of the nature of cobalt complexes and the experimental conditions (presence of ligand [such as P(OPh)3 or pyridine], or/and of Lewis acid [ZnCl 2, AlCl3], organic solvent or ionic liquid), the product of isomerization 2-methyl-2-butenenitrile was obtained instead of the expected rearranged product 3-pentenenitrile (3PN). This result was explained by the activation of CH bond instead of CCN bond. With 3PN, the first example of a reversible cleavage of the CCN with complex derived from Co+ was evidenced.
