Thermal Cleavage

The zerovalent iron complex Fe(PMe3)2(t-BuNC)3 undergoes thermal cleavage of the C—N bond to give Fe(PMe3)2(t-BuNC)2(H)(CN) and isobutylene. The reaction follows first order kinetics, and addition of the hydrogen-atom donor 1,4-cyclohexadiene leads to the preferential formation of isobutane rather than isobutylene. Mechanistic studies are consistent with a rate determining homolysis of the C—N bond, giving rise to tert-butyl radicals.Key words: iron, isocyanide, elimination, C—N cleavage.
