" Rhodium Nitrene " and selective C(sp3)-H bond amination. Iron and hydroxylamine : a long-lasting couple for amination reactions

Two presentations examine selective nitrogen installation in organic molecules. The first studies how changing rhodium nitrene catalysts can direct amination toward different carbon–hydrogen bonds, including normally unreactive sites, beyond the limits of substrate-directed approaches. The second addresses the sustainability problems of scarce metals and conventional nitrene precursors through iron catalysts and hydroxylamine derivatives. Applications include aziridination, alkene difunctionalization within and between molecules, and direct carbon–hydrogen functionalization without an additional external oxidant.
