Abstract
Halo-(carbonyldioxyaryl)ethylenes are prepared by a catalytic process which comprises contacting a halo-bis(hydroxyaryl)ethylene, carbon monoxide, an oxidant, a base, and a Group VIIIB element selected from ruthenium, rhodium, palladium, osmium, iridium or platinum. The resulting halo-(carbonyldioxyaryl)-ethylenes are useful as flame retardents for thermoplastic polymeric materials.
