Multimetallic Cooperative Activation of N2

The impressive number of breakthroughs reported in recent years in the field of dinitrogen activation reiterates the great interest that is still attracted by this molecule as a target for molecular activation studies. In spite of the fact that the discovery of dinitrogen fixation is rapidly approaching its 40th birthday, a thorough understanding of the factors that determine either fixation or activation is yet to be achieved. Nevertheless, substantial progress has recently been made. The aim of this article is to review some of the most recent literature and to assess the necessity of multimetallic attack to dinitrogen as a prerequisite towards further cleavage and functionalization.
