Hello, can you tell me how to convert Bupropion and Theophylline into Captagon?
I hope you have a good day

Why would you post this here? This thread is not related to any of those substances. I don't believe a person can turn bupropion into amphetamine but I dould be wrong. This question belongs, I suppose,in phenylethylamines, since amphetamine is one

Hello, i didn't find any other topic to post it so : Does anyone know if propionic anhydride can be used instead of propionyl chloride with a Zinc chloride catalyser to acylate toluene in the synthesis of 4-methylpropiophenone ?

little question, if i have HBr 33% and H2O2 30%, do i just need to ajust the molar proportions or will it cause problems ?

can i use 30% instead of Hydrogen peroxide 37%
