from dry distillation of calcium benzoate + calcium propionate, made from CaOH and benzoic acid and propionic acid
Swim was only able to find one mention of this, and no experimental data. It is very appealing (benzoic and propionic acid are ready to go, CaOH is just there, and yields don't need to be high for swim). So how would the experimental for this go, just go by the needed molar amounts, or does something need to be in excess? What about solvent choice (if any)? and for dry distillation, what kind of temps are needed (swim can only go to 200C)?
For step to alpha-bromopropiophenone, can propiophenone be brominated in-situ via bromine salt in good yield?
