Aziridinierung eines einzelnen Kohlenstoffatoms in Alkenen mittels Energietransferkatalyse

open access: yesAngewandte Chemie, EarlyView.
Im Gegensatz zur traditionellen Alken‐Aziridinierung über (formalen) Nitren‐Transfer berichten wir hier über eine Strategie zur intermolekularen Aziridinierung eines einzelnen Alken‐Kohlenstoffatoms bei zusätzlicher Funktionalisierung der anderen Position. Durch Energietransfer‐ (EnT‐)Katalyse werden Alkenylboronate und ‐silane in reaktive Intermediate
