Halocarbon photooxidative addition

Figure 4. Proposed general mechanistic scheme for halocarbon photooxidative addition to binuclear Ir(l) and Pt(II).

This binuclear photooxidative addition reaction is general for a number of halocarbons (Figure 3). While DCE and 1,2-dibromoethane react cleanly to give the dihalide metal dimers and ethylene, substrates such as bromobenzene or methylene chloride react through an alkyl or aryl intermediate. This intermediate reacts further to yield the dihalide d2-d2 metal complexes. 

Photooxidations of Halocarbons. In addition to the photoreduction pathways, other indirect photochemical reactions are significant in the oxidation of halogenated organic compounds. These reactions were reviewed else-...
