Selektivno bromiranje lahko izvedete tudi z bakrovim (II) bromidom

Opišite, kaj imate v mislih. Ali bo bakrov bromid nadomestilo na istem mestu, če da, kakšni so reakcijski pogoji/format?

Ne. pojavijo se težave s čistostjo in izkoristkom.
Da, vendar so mehanizmi reakcij nekoliko drugačni.

Priprava 2-jodo-4-metilpropiofenon Tako imenovani jodoketon V čašo damo 4-metilpropiofenon 150 ml (148,90 g) N-jodosucinimid 270 g Monohidrat P-tulenesulfonske kisline 228 g Kozarce ne tesno pokrijemo s steklenim pokrovom. Postavimo v mikrovalovno pečico in jo nastavimo na 700 W. Osvetljujemo trikrat po 1 minuto s 30-sekundnimi prekinitvami med posameznimi seansami. Počakamo, da se romantika ohladi na temperaturo. Vanjo vlijemo 300 ml notranje vode z ledom in jo temeljito premešamo. Jodoketon bo nastal skoraj takoj Prefiltriramo na filtru in še 2 ali 3 krat speremo vodo Kristalizacija 1g jodoketona dodamo 0,5ml ali 0,7ml dcm zmešamo v posodi in damo v zamrzovalnik -20 čez noč Po noči filtriramo in nato posušimo. Izdelek 210 g do 215 g čistega jodoketona bo v redu?

Ali se lahko uporablja nano bakrov oksid? Ali bo naknadna obdelava problematična?

manjša kot je mreža oksida, težje ga bo ločiti od zmesi

Seveda bo iz propiofenona nastal metkatinon. Metode so, afaik, enake; preprosto ga zamenjajte in izvedite aritmetiko z moli itd. Vendar, tako kot tema, tudi jaz nisem kemik.
