no, most reagents/ reaction conditions that will reduce the benene ring(ie. raney nickel or pd carbon under pressure) will destroy your functionality.

Hmm you could try a birch reduction maybe to get it to a diene and form there not sure how ya might gop about reducing the other double bonds, maybe
NaBH4 but i aint sure.

Well, http://www.pubmedcentral.gov/articlerender.fcgi?artid=93338 says | Quote: | | The anaerobic bacterium Syntrophus aciditrophicus metabolized benzoate in pure culture in the absence of hydrogen-utilizing partners or terminal
electron acceptors. The pure culture of S. aciditrophicus produced approximately 0.5 mol of cyclohexane carboxylate and 1.5 mol of acetate per mol of
benzoate |
The start of an article using platinum and haloacid, you'll need to get the full article to see if it works for you

Ah, thank you ziqquratu! Not only does that look as if would be useful to enkay, it might do the trick when one needs a small amount of some
cycloalkanes. It also appears that short reaction times could be used to remove a halogen from an aromatic, although you'd probably want to recycle
unreacted material.
