Are cineva informații despre bromurarea 2C-H cu n-bromosuccinimidă? Am văzut câteva persoane care au menționat acest lucru în altă parte, dar nu am găsit niciun articol.

Și eu caut acest lucru, dar nu am putut găsi informații detaliate
Ceea ce știu este că se poate face în GAA sau DCM, dar nu am idee despre raport

Am o îndoială cu privire la ultimul pas al sintezei 2CB. Se spune "Amestecul de reacție a fost lăsat să revină la temperatura camerei, filtrat, iar solidele au fost spălate cu moderație cu acid acetic rece" până când știu că acidul acetic devine solid la 16-17C, deci ce înseamnă mai exact acid acetic rece?
Mulțumesc.

Bună. Presupun că acidul rece înseamnă temperatura camerei deoarece există o explicație conform căreia reacția eliberează căldură.

Bine, bine, și eu am crezut asta, dar am preferat să confirm, după cum știți, când spunem rece, în mod normal, ne referim la congelator, nu la RT hahaha, dar cu acid acetic nu este posibil ;-) mulțumesc

Nu prea înțeleg de ce spălați hidrobromura de amină, este imposibil să o folosiți, arde. Este mai bine să purificați și să obțineți clorhidrat și pierderile sunt mai mici, pentru a evita încercările dubioase de spălare a pulberii de brom.

Înțeleg că bromul elementar rămas se va evapora în aer din produs, la fel ca orice solvent, astfel încât nu va mai exista nicio cantitate rezonabilă rămasă cu timpul. Producerea HCL fără uscarea HBr - mult noroc pentru a obține un produs mai pur, deoarece este posibil să aveți de-a face cu sărurile de brom din soluția brom/GAA și cu bromul în sine.

Nu văd nicio problemă în a bate resturile de brom cu tiosulfat, apoi aduceți ph-ul la un mediu alcalin și colectați uleiul cu un solvent.

(R)-(+)-α-metilbenzilamină Număr CAS:
3886-69-9 Se elimină din plămâni? Sau este absorbită de stomac? Poate fi utilizată direct?

Condensarea Henry a 2,5-dimetoxibenzaldehidei cu nitrometan în prezența unei amine primare ca catalizator.

este posibilă înlocuirea bromului elementar cu acid hbr? în sinteza 2cb?

Question to you guys.Is it possible to perform bromination of 2ch to 2cb by NBS (N-Bromosuccinimide)
instead of elemental bromine (br2)

i found some writeups on thehivee but im not sure about it i also cant try do it on my own. but NBS seems to be safer to use than BR

I use a 2×2×4 grow tent in its side with a 8" inline fan going out the building as a hood up on a folding table definitely does the job,still wear a mask non the less. Make sure you have a 5% sodium thiosulphate solution on hand in case of a accident and a rubber made bin with enough of that solution to run through you glass at the end.and think every step out. You got this my friend can't wait to hear of your success.

Sure you can, obviously dig as deep as you can researching hand but the fact you came this far says a lot.so keep pushing and if you waste something you at least gain the experience.now safety if thats what your concerned about thats a horse of a different color

I just wanted to say thanks for this incredibly involved set of syntheses.
It is really impressive.
It’s funny, I made quite a few different nitrostyrene’s and nitropropene’s and then when I started reducing them and getting decent yields on active molecule’s, I started thinking okay, well it can’t be that much harder to produce the 2c-x compounds, then you see people making 2c-b and presumably other haloginated 2c’s and you think ah okay.

Then you start digging into the alkylated 2c compounds and my oh my does the chemistry take a jump in complexity!!

Anyway, I’m pretty convinced that my next major project is going to have to be the ethylated 4 position.
Is that a friedl-crafts alkylation you do to the 2,5-dimethoxyacetophenone, I mean in order to get from that to the 2,5-dimethoxy-1-ethylbenzene?

I think the most annoying part of it is that I’m going to have to get a vacuum pump that runs to super high vacuum!

Anyway, be prepared to be bugged by me a lot in the coming months/years because once I set my mind to something, I WILL learn how to get it done. It often involves harassing old posters! Ha
