WebMar 22, 2024 · Herein, the first radical asymmetric aminoazidation and diazidation on acyclic systems via radical rebound is reported. Abstract Asymmetric aminoazidation and diazidation of alkenes are straightforward strategies to build value-added chiral nitrogen-containing compounds from feedstock chemicals. WebJul 2, 2024 · The radical intermediates in pathway A, that is, 4,2 IM1 HA,A, are characterized as local minima on the potential energy surface, with real frequencies only. However, the radical rebound barriers for both spin states were found to be very low in energy (<1 kcal mol −1) and hence could not be characterized. Therefore, the radical intermediates ...

WebThis caged radical pair then evolves on a complicated energy landscape through a number of reaction pathways, such as oxygen rebound to form R-OH, rebound to a non-oxygen atom affording R-X, electron transfer of the incipient radical to yield a carbocation, R +, desaturation to form olefins, and radical cage escape. WebAs we shall see, the radical rebound mechanism proposed in this work is kinetically equivalent to the concerted mechanism proposed before and provides an alternative pathway for this reaction to take place. In addition, the accuracy of the B3LYP functional was assessed with the results obtained from the CCSD (T)-F12 method for a small model.
