Secondary alcohols never become aldehydes or acids. Primary alcohols go through those reactions, and secondary alcohols become ketones.
The other side product of this reaction would be 2-phenyl-1-propanol, which would oxidize to 2-phenylpropanal, which in turn can stil be changed into P2P a la Rhodium's site, with H2SO4 or HgCl2.
The phenylpropyl alcohol would oxidize to phenylpropanal, the aldehyde, or phenylpropionic acid, the carboxylic acid.
