Dobrý deň,
Urobil som 3 mmc bieleho Sythese z videa, reakcia je tiež rovnaká a všetko išlo dobre. Urobil som pekne vyzerajúce kryštály, ale efekt nie je dobrý, myslím, že je to 2-bróm-3-metylpropiofenónom z Číny.
Vyrobil niekto 3 mmc alebo mal tento problém, môže mi pomôcť

Priateľ sa pokúsil urobiť rovnakú syntézu ako na 4cmc, ale teraz na 2bromo 3 chloro. Najskôr prišla voľná báza tmavo oranžová, v prípade 2bromo 4 chloro je jasne zlatá. Potom sa po okyslení HCL zmenila na čiernu. Vie niekto prečo? Ph na 5-6
