Abstract

Catalytic dehalogenation of fluorinated and chlorinated ethylenes by (PPh 3) 3RhCl in the presence of Et 3SiH at 35 °C is described, and product identity and kinetic parameters were determined. This system has an intramolecular preference for Cl over F removal, an intermolecular preference for F- over Cl-containing alkenes, and a strong preference for sp 2 over sp 3 carbon-halogen bonds. Both the substitution pattern and the substituent identity are important in determining the rate of the dehalogenation.
