If you haven't got a dedicated leaf bin, then collect them in black binliners, wet them well, tie the liners and puncture several times. Forget about them - except to spray through the holes in dry weather. Leaves decay through a different process from that found in a compost heap (he said, avoiding getting technical!)
it'll take forever as some leaves rot better than others..if you dont mind a year or 18mths then grand.
personnally id put them in your green bin garden waste kind)
