Preconversion catalytic deoxygenation of phenolic functional groups
The deoxygenation of phenols is a conceptually simple, but unusually difficult chemical transformation to achieve. The phenolic C-O bond energy of 103 kcal/mol is an strong as a benzene C-H bond and over 10 kcal/mol stronger than the C-O bonds of methanol and ethanol. The consequence of this is that the hydrogenation/deoxygenation methods in current use require severe conditions and give low selectivities. The ongoing research described herein is based on the uprecedented, but thermodynamically promising, use of carbon monoxide as the oxygen atom acceptor for the catalytic deoxygenation of phenols. Catalytic activities of Ir(triphos)OAr and (Ir(triphos){eta}{sup 4}-cod)Cl are described. 25 refs., 3 figs.
