How are phenols made?
That reaction will definitely not yield a phenol.
Phenols are not usually prepared directly from benzene, but from benzene derivatives, such as toluene or chlorobenzene:

Oxidation of toluene, as developed by Dow Chemical:

$\ce{C6H5CH3 + 2 O2 → C6H5OH + CO2 + H2O}$

Hydrolysis of chlorobenzene, using base or steam (Raschig–Hooker process):

$\ce{C6H5Cl + H2O → C6H5OH + HCl}$

Actually, there are processes that allow us to obtain it directly from benzene, but these are rarely used:

Direct oxidation of benzene with nitrous oxide, a potentially "green" process:

$\ce{C6H6 + N2O → C6H5OH + N2}$

The most widely used process for industrial production (95%) involves the partial oxidation of cumene (isopropylbenzene) via the Hock rearrangement:

$\ce{C6H5CH(CH3)2 + O2 → C6H5OH + (CH3)2CO}$
