Abstract:Di‐π‐methane rearrangement in a phosphorus compound The present manuscript reports on the synthesis of the first pyridyl‐functionalized 1‐phosphabarrelene from the corresponding heteroaromatic phosphinine and hexafluoro‐2‐butyne. This P,N‐hybrid ligand readily forms coordination compounds with RhI, W0, and Fe0 and undergoes a rather selective photochemical di‐π‐methane rearrangement in the coordination sphere of the metal center to afford a novel 5‐phosphasemibullvalene derivative. DFT calculations provide fir… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
