3-Rhoda-1,2-dioxolanes through Dioxygenation of a Rhodium-Ethene Complex by Air

Proposed as intermediates in the catalytic oxidation of olefins to ketones, 3‐rhoda‐1,2‐dioxolanes (κ2C1,O2‐2‐peroxyethyl rhodium complexes) have now been prepared by oxygenation of solid [(N4‐ligand)RhI(ethene)]PF6 (see scheme) with air. This process leads to stable isomeric 3‐rhoda‐1,2‐dioxolanes...

Description
Summary:Proposed as intermediates in the catalytic oxidation of olefins to ketones, 3‐rhoda‐1,2‐dioxolanes (κ2C1,O2‐2‐peroxyethyl rhodium complexes) have now been prepared by oxygenation of solid [(N4‐ligand)RhI(ethene)]PF6 (see scheme) with air. This process leads to stable isomeric 3‐rhoda‐1,2‐dioxolanes A and B. Upon substitution of PF6− by BPh4− only isomer B is obtained. The X‐ray structure of isomer B is presented.
