Synthesis and structure of the adduct Cl3AsO·AsF5
Abstract
The relatively thermally stable adduct Cl3AsO·AsF5 1 is prepared in high yield from AsCl4+AsF6– and Me3SiOSiMe3 in liquid SO2 at –40 °C, and originally surprisingly isolated from the reaction of PrCl3 and AgAsF6 in liquid SO2; the X-ray crystal structure of 1 is compared with that of Cl3PO·AsF5.
