Reduction of aromatic ketones to alkanes with Pd/C and hydrogen

Description: When treated with a metal catalyst such as palladium (Pd) or platinum (Pt) and hydrogen gas (H2) ketones next to aromatic groups are converted into alkanes.

Notes: This does not work for ketones that are not adjacent to aromatic groups.


Notes: Note that the fourth example has a non-aromatic ketone. These are not reduced to alkanes.

Mechanism: For the purposes of Org 1/ Org 2 the mechanism of this reaction is not that important. For more information on the reaction, consult “Advanced Organic Chemistry” by Smith and March.
