Ok, just read that thread. Hmmm...SWIM thinks that HBr in GAA would have less variables that could cause things to fuck up than a DMSO/NaBr/H2SO4 synth.
Question to anyone who knows:
-->if one had a solution of GAA/HBr/H2O, could some kind of drying agent be added to romove some of the water???
Would this even be necessary??
What drying agent would be suitable? need something not soluable but capable of absorbing the water but not the GAA or HBr.
If some or all of the water could be removed this way, improv thinks that the resulting GAA/HBr solution would definately brominate safrole to the bromocompound we are looking for.
Has anyone used silica gel for drying??
Will this stuff absorb GAA or HBr? H2O is a smaller molecule than both...
If not SWIM might be going to the flower shop....
Other than that improv thinks that if HBr(g) could be obtained, bubble it into some GAA with a fish tank airator and add the saf....THAT would be the way improv would do it if improv played with these sort of thing... But improv doesn't do these kind of things, that's left up to my friend SWIM to play with......
I think that the only concern would be to not get any Br2(g) with the HBr(g) for the bubbling.
hmmm...mabe that old acid distillation aparatus to make some HBr(aq)....
we shall see...
ps: SWIM used Dr. StrangeGlove's(sp?) revised DMSO recipe when he did the rxn with NaBr, that synth uses less NaBr and Sulfuric than pugsley's version........you can find it on the old board..
If it doesn't work, smash it and start over
