Cover Feature: Pyridyl‐Functionalized 1‐Phosphabarrelene: Synthesis, Coordination Chemistry and Photochemical di‐π‐Methane Rearrangement (Chem. Eur. J. 63/2019).

Keywords: coordination chemistry; DFT calculations; di-pi-methane rearrangement; phosphabarrelene; phosphorus ligands This P,N-hybrid ligand readily forms coordination compounds with Rh SP I sp , W SP 0 sp , and Fe SP 0 sp and undergoes a rather selective photochemical di- -methane rearrangement in the coordination sphere of the metal center to afford a novel 5-phosphasemibullvalene derivative. Coordination chemistry, DFT calculations, di-pi-methane rearrangement, phosphabarrelene, phosphorus ligands. [Extracted from the article]
