Rücktitelbild: Locking the Conformation of a Paddlewheel Rhodium Complex: Design, Synthesis, and Applications in Catalytic Nitrene Transfers (Angew. Chem. 51/2023)
Graphical Abstract
Two structures of paddlewheel rhodium complexes displaying either syn or anti conformations are shown in the cover picture. Each of them stands on a separated podium, indicating that two conformations are not in an equilibrium and thus do not undergo interconversion. The conformational fixation has proven to be useful for the development of selective nitrene transfer catalysts, as demonstrated by Xinxin Tang, Hidetoshi Noda, and Masakatsu Shibasaki in their Research Article (e202311027).
