¿Alguien tiene información sobre la bromación de 2C-H con n-bromosuccinimida? He visto que algunas personas lo mencionan en otros sitios, pero no he encontrado ningún artículo.

Yo también estoy buscando esto pero no he podido encontrar la información detallada
Lo que sé es que se puede hacer en GAA o DCM pero ni idea de la proporción

Tengo una duda sobre el último paso de la síntesis de 2CB. Dice "La mezcla de reacción se dejó volver a temperatura ambiente, se filtró y los sólidos se lavaron escasamente con ácido acético frío" hasta que sé que el ácido acético se solidifica a 16-17C así que ¿qué significa exactamente ácido acético frío?
Gracias.

Hola. Supongo que el ácido frío se refiere a temperatura ambiente porque se explica que la reacción libera calor.

No entiendo muy bien por qué lavar el hidrobromuro de amina, es imposible usarlo, se quema. Es mejor purificar y obtener el clorhidrato y las pérdidas son menores, como para evitar dudosos intentos de lavar el polvo de bromo.

Entiendo que el bromo elemental restante se va a evaporar en el aire del producto, como cualquier disolvente, por lo que no quedará ninguna cantidad razonable con el tiempo. Hacer HCL sin secar HBr - buena suerte para obtener un producto más puro, porque puede que tengas que lidiar con sales de bromo en la solución de bromo/GAA, y con el propio bromo.

No veo ningún problema en batir los restos de bromo con tiosulfato, luego llevar el ph a un medio alcalino y recoger el aceite con un disolvente.

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
