Thiocaprolactam reacts with ironpentacarbonyl in the presence of dibutylether solvent at 100℃ under nitrogen to give the corresponding desulfurized cyclic Schiff base. And then a variety of benzaldehyde derivatives react with reaction mixture including Schiff base in the presence of the synthesized tetracarbonyl-hydridoferrate at room temperature under an atmospheric carbon monoxide to give the corresponding N-substitute perhydroazepines in good yield.
The mechanism of these reactions is investigated.
