The deoxygenation of phenols by carbon monoxide mediated by Ir(triphos)(OAr) has provided us with a catalytic phenol deoxygenation pathway, through the elimination of CO{sub 2} and formation of a benzyne intermediate. Although the (Pt(triphos)(O-Ph- Me))PF{sub 6} system is not expected to be as efficient a catalyst as come of the other transition metals systems we are currently exploring, it will provide more information about the deoxygenation mechanism in these triphos complexes. This is due to the presence of the structurally sensitive {sup 31}P-{sup 195}Pt coupling constant and comparisons to the extensively studied Pt(dppe)(O-Ph){sub 2} systems.
