The present invention provides a method for producing caffeine, wherein the method comprises: (a) combining a coffee extract comprising caffeine with an aqueous organic acid; (b) crystallizing the coffee extract and the aqueous organic acid so as to form caffeine-organic acid co-crystals in an aqueous phase; (c) separating the caffeine-organic acid co-crystals from the aqueous phase; and (d) extracting caffeine from the co-crystals obtained in step (c), wherein step (d) comprises placing the co-crystals in an aqueous solution so as to form a caffeine precipitate and a solution comprising the organic acid. Also provided is a method for producing a decaffeinated coffee extract comprising chlorogenic acids.

The present disclosure relates to reagents and method for performing trifluoromethylation, difluoromethylation or alkylation of aromatic or heteroaromatic rings in a redox-neutral manner without any catalyst which are enabled by light. In addition, there are methods for synthesizing the starting reagents used in the trifluoromethylation, difluoromethylation or alkylation reactions.
