High-valent metal-imido species with late metals of the first transition series

Abstract

The conversion of C-H bonds into C-N bonds is a process of great interest due to the presence of nitrogenated fragments in several relevant organic architectures. A sustainable way of performing this transformation consist in reaction of a metal catalyst with a nitrene source, giving rise to the formation of high-valent metal-nitrogen compounds. In this paper, the most relevant examples of these species based on late first row transition metals such as Fe, Co or Ni are described. Special emphasis is paid on Cu complexes, which have been widely applied in these transformations.
