N‐Carboranylamine …… sind hochinteressante Verbindungen für die medizinische Chemie und die Katalyse. Ihre Synthese allerdings ist schwierig. In der Zuschrift auf S. 1783 ff. beschreiben Z. Qiu, Z. Xie et al. einen Ansatz, der die neue Carborinvorstufe 1‐OTf‐o‐C2B10H11 nutzt. Diese reagiert sehr effizient mit Lithiumamiden zu einer Vielzahl an N‐Carboranylaminen.
The efficient o‐carboryne precursor 1‐Li‐2‐OTf‐o‐C2B10H10 reacts with lithium amides at room temperature to give a series of N‐carboranyl amines in moderate to high isolated yields. This reaction is compatible with a broad substrate scope from primary to secondary, alkyl to aryl amines. The reaction mechanism is also proposed on the basis of experimental results and DFT calculations. This represents...
