C-H amination by iron-imido/nitrene species has attracted increasing research interest in recent years because of its potential use in economical and environmentally benign syntheses of amino compounds.With the aim of providing a comprehensive overview of this field,which is of interest to both the synthetic organic and inorganic communities,this paper reviews the status quo of C-H amination chemistry by iron-imido/nitrene intermediates,as well as by well-defined iron-imido/nitrene compounds,with special emphasis on their structure/reactivity correlations.Achievements,problems,and perspectives in this growing field are discussed.
