Abstract

Unlike typical homodinuclear high‐valent [M2(μ‐O)2]n+ cores, a rare heterobimetallic high‐valent CuNi bis(μ‐oxo) complex behaves as a nucleophile. In their Communication on page 5622 ff., K. Ray, M. Driess, C. Limberg et al. show that this complex can initiate deformylation of aldehydes, indicating that mixed‐metal bis(μ‐oxo) cores are viable intermediates in the deformylation of fatty aldehydes by cyanobacterial aldehyde decarbonylase, for which a similar cofactor has been suggested, but not isolated.
