Pozdravljeni,
Naredil sem 3 mmc bele Sythese iz videoposnetka, reakcija je tudi enaka in vse je šlo dobro. Naredil sem lepo videti kristale, vendar učinek ni dober, mislim, da je kriv 2-bromo-3-metilpropiofenon iz Kitajske.
Ali je kdo naredil 3 mmc ali imel to težavo, mi lahko pomaga.

Prijatelj je poskušal opraviti enako sintezo kot na 4cmc, vendar zdaj na 2bromo 3 kloro. Najprej je prišla prosta baza temno oranžne barve, v primeru 2bromo 4 chloro pa je svetlo zlata. Nato je HCL po zakisanju postal črn. Ali kdo ve, zakaj? Ph na 5-6
