Witrynapeptization are caused by hydrogen abstraction from the rubber molecule, and the unstable radicals produced from reagents having great affinity to the hydrogen atom may be suitable as an initiator for these reactions. These compounds may involve 0-, S- and N-radical components. The activity of radicals depend also upon their stability. WitrynaTwo superficial oxygen atoms were decorated with two hydrogen atoms. The second model was built by attaching a TcO 2 fragment to two superficial oxygen atoms, forming a TcO 4 species embedded into the surface. The four superficial undercoordinated Fe Oct atoms were saturated by one H 2 O molecule and three OH groups. No …
