Cleavage of benzyl group from alkane?
The following is just a mind game: 


Oxidize at the benzylic position to get an arylketone using oxone
Convert the ketone to an ester by Baeyer-Villiger reaction
Cleave the ester
Run a Barton-McCombie deoxygenation on the resulting alkanol


Please note that I havent't done it and I'm not planning to. I'd rather try to avoid the benzyl group in the starting material if possible.
