Czy ktoś ma informacje na temat bromowania 2C-H za pomocą n-bromobursztynoimidu? Widziałem kilka osób wspominających o tym gdzie indziej, ale nie znalazłem żadnych opisów.

Też tego szukam, ale nie mogłem znaleźć szczegółowych informacji
Wiem, że można to zrobić w GAA lub DCM, ale nie mam pojęcia o proporcjach.

Mam wątpliwości co do ostatniego etapu syntezy 2CB. Napisano "Mieszaninę reakcyjną pozostawiono do powrotu do temperatury pokojowej, przefiltrowano, a substancje stałe przemyto oszczędnie zimnym kwasem octowym", dopóki nie wiem, że kwas octowy staje się stały w temperaturze 16-17 ° C, więc co dokładnie oznacza zimny kwas octowy?
Dzięki.

Witam. Zakładam, że zimny kwas oznacza temperaturę pokojową, ponieważ jest wyjaśnienie, że reakcja uwalnia ciepło.

Ok ok też tak myślałem ale wolałem potwierdzić jak wiesz kiedy mówimy zimny normalnie mamy na myśli z zamrażarki a nie RT hahaha ale z kwasem octowym to niemożliwe ;-) dzięki

Nie bardzo rozumiem, po co myć bromowodorek aminy, nie da się go używać, pali się. Lepiej oczyścić i otrzymać chlorowodorek i straty są mniejsze, jak uniknąć wątpliwych prób wyprania proszku z bromu.

Rozumiem, że pozostały brom pierwiastkowy wyparuje w powietrzu z produktu, tak jak każdy rozpuszczalnik, więc z czasem nie pozostanie żadna rozsądna ilość. Wytwarzanie HCL bez suszenia HBr - powodzenia w uzyskaniu bardziej czystego produktu, ponieważ możesz mieć do czynienia z solami bromu w roztworze bromu/GAA i samym bromem.

Nie widzę problemów, żeby ubić resztki bromu tiosiarczanem, potem doprowadzić ph do zasadowego i zebrać olej rozpuszczalnikiem.

(R)-(+)-α-metylobenzyloamina Numer CAS:
3886-69-9 Czy wydostaje się z płuc? Czy jest wchłaniany przez żołądek? Czy można ją stosować bezpośrednio?

Henry kondensacja 2,5-dimetoksybenzaldehydu z nitrometanem w obecności pierwszorzędowej aminy jako katalizatora.

czy można zastąpić pierwiastkowy brom kwasem hbr w syntezie 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 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
