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.

  1. What is the difference between H2, Pd and H2, Pd/C/

    Does H2, Pd only reduce ketones to alkanes?

    Does H2, Pd/C reduce alkenes to alkanes?

  2. Can a secondary ketone be reduced to an alkane by H2, Pd/C if it’s not aromatic? If not, what would you use?

    1. Ketones can be reduced to alcohols using Pd/C with enough pressure of H2, but to go down to the alkane, it’s necessary to convert the OH into OTs (or OMs) and treat with LiAlH4. Essentially a substitution reaction occurs forming C-H and breaking C-O .
