and kinetically competent catalysts for this transformation. The fleeting transmetalation intermediate has been successfully synthesized through an alternative synthetic organometallic pathway at lower temperature, allowing for in situ NMR study of the C–N bond reductive elimination step. This study addresses key factors governing the mechanism of the nickel-catalyzed Buchwald–Hartwig amination process
only in the fundamentals but also in the economic and ecological fingerprint of organic reactions. Here we show that few-layer black phosphorous (FL-BP), a recently discovered and now readily available 2D material, catalyzes different radical additions to alkenes with an initial turnover frequency (TOF0) up to two orders of magnitude higher than representative state-of-the-art metal complex catalysts
Salt and iron ease the way to amines Adding nitrogen to carbon compounds is often a laborious process. The nitrogen typically needs protection to prevent undesired reactivity, and the protectinggroups can be hard to remove afterward. Legnani et al. report a versatile method to add unadorned NH2 from a hydroxylamine derivative directly to a double-bonded carbon center. A simple iron catalyst manipulates
