What compounds would be required for a photosynthetic reaction resulting in flourine gas?

Primordial Earth was buried in carbon dioxide. When life started, it was with algae using energy from the sun to crack the carbon out of carbon dioxide, with the byproduct of releasing the corrosive and toxic oxygen gas into the air. From there we get animals that use said oxygen, and so on with increasing complexity.

So, to get sapient species that breathe fluorine gas in a similar manner as we do oxygen, we must begin at the beginning, with plants. What compounds would need to exist in abundance on a primordial planet in order for a photosynthetic reaction that results in fluorine as a waste product to occur?
