The chemistry is a bit vague for laymen, but essentially, regions of star formation can create a lot of heat, which allows free oxygen radicals to be scavanged (picked up by bonding) by hydrocarbon molecules present in the clouds.
Neutral number densities in space are usually too low to get significant amount of these products, even on universal time scales. They are usually proposed to occur via ion/molecule reactions, which occur a lot faster (because of electrostatic attraction). The last step ends up being a neutralization of some sort (proton transfer, electron transfer, or even electron capture)
