Cover Feature: Sequential H/D Exchanges Resulting from Rollover‐Cyclometallation during Photoirradiation of Rhodium(III) Complex in Methanol‐d₄ (Chem. Eur. J. 63/2024)

A group of four white discs at the center of the Othello board represents the pyridine rings of the complex [Rh(N^N)2]+. The complex undergoes rollover cyclometallation of one of the pyridine rings to afford [Rh(N^N)(C^N)(H)(CH3OH)]+, [Rh(N^N)(N^C)(H)(CH3OH)]+, [Rh(C^N)(N^N)(H)(CH3OH)]+, or [Rh(N^C)(N^N)(H)(CH3OH)]+ at the same probability, which are represented as groups of one black disc and three white discs. Upon irradiation (white beam), every black disc turns over to return to the group of four white discs. More information can be found in the Research Article by K. Shinozaki and co-workers (DOI: 10.1002/chem.202402067).
