Photocatalytic Reactions Involving Diazo Compounds as Radical Precursors

Diazo compounds are important synthons which have attracted condirable attentions by synthetic chemists. They can server as carbene precursors, 1,3-dipoles, C-nucleophiles, terminal N-electrophiles and radical intermediates. In recent years, the photocatalytic generation of radicals from diazo compounds has made remarkable development. In this review, the recent developments in this research field are summarized which mainly focus on the generation of diazomethyl radical, carbon radicals, carbyne radicals and allene radicals from diazo compounds. Moreover, the future development direction, as well as challenges in this field is prospected.
