It is always best to compost the leaves fully before using them in the soil. It can be used as a mulch, but unmulched oak leaves can rot, or even slightly change the soil pH. I would not recommend this. If you decide to do this still, then you will want to add mycorrhizae to the soil to help it break down faster.
