Experimental and Theoretical Characterization of the Oxygen-Coordinated Donor-Adducts of COCl2, COClF and COF2 with AsF5 and SbF5

Abstract

When reacted with an excess of the corresponding carbonyl halides, AsF5 and SbF5 from the following 1:1 adducts: COCl2*AsF5, COCl2*SbF5, COCIF*AsF5, COClF*SbF5, COF2*AsF5 and COF2*SbF5. All adducts are unstable at ambient temperature, and their dissociation enthalpies were determined from the dissociation pressure curves. Vibrational and multinuclear NMR spectra and theoretical calculations show that all compounds are oxygen-coordinated donor-acceptor adducts, and that the strengths of the oxygen-bridges increase from COF2 to COCl2 and from AsF5 to SbF5.
