The Far Side of Carboranes: Anticancer Active Monocations and Ambiently Stable Dications
Angewandte Chemie, EarlyView.This work describes the synthesis of bench‐stable dicationic carboranes. Their enhanced electrophilicity is documented by opening the clusters with weak nucleophiles or dihydrogen. The surprising stability of positively charged carboranes in water enabled a study of their in vitro antiproliferative activity, which surpassed the effects of doxorubicin ...

A Free N‐Heterocyclic Carbene and Its Metal Complex
Angewandte Chemie, EarlyView.Free N‐heterocyclic carbenes (NHCs) are directly visualized on ultrathin sodium‐chloride films on gold (NaCl/Au(111)) using scanning tunneling microscopy (STM), atomic force microscopy (AFM), and density functional theory (DFT). Submolecular imaging reveals their structure and frontier orbital.
