Metal–Metal Cooperative C─F and S─F Bond Cleavage by Low‐Valent Tetracobalt Clusters and Water‐Assisted Fluoroarene Hydrodefluorination

Angewandte Chemie, EarlyView.
Self‐assembled tetrahedral CoI4 clusters supported by simple bipyridine‐based ligands undergo core rearrangement to cleave S─F and C(sp2)─F bond, forming fluoride‐bridged tetracobalt(II)‐oxo clusters, while exposure of cobalt(I) clusters to molecular oxygen yields cubane‐type cobalt(III) oxo clusters.

Milankovitch Cyclicity and Stable Isotope Calibration in the Paleogene (invited)

, 2003
Significant progress has been made over the last decade in the extension of astronomically calibrated geological time scales for the Neogene (Hilgen et al., 1999, Shackleton et al., 1999).

Gain‐of‐Function Engineering of the NifEN Scaffold Into a Self‐Assembling Nitrogenase

Angewandte Chemie, EarlyView.
From scaffold to enzyme: Systematic engineering of the cofactor maturation scaffold NifEN reconstructs the P→M electron relay along with cofactor coordination and proton gating at the S2B site, converting NifEN into a functional nitrogenase capable of ATP‐dependent N2 reduction both in vitro and in vivo.

Induction of Methuosis in Breast Cancer Stem Cells by a Cobalt(III) Complex Evokes Immunotherapeutic Response

Angewandte Chemie, EarlyView.
Cancer stem cells (CSCs) drive metastasis, relapse and resist conventional apoptosis‐inducing chemotherapies. We report a cobalt(III)‐cyclam complex with pyrene and diflunisal moieties that reduces the viability of breast CSCs at low micromolar concentrations.
