different halogens and the subsituion

Madandcrazy - 1-2-2006 at 08:03

How are the different reaktions conditions by a substitution
with any holgens.

I will start with 1-flouro-3-bromo-5-chlorocyclooctane ;) and will the anilin with one of the halogens transposing, for instance to 1-benzylamin-3-bromo-5-chlorocyclooctane.

Is it depending of a specific themperature or dependently of
spezial chemicals.

Fluorine is so damn clingy to carbon that the transformation you propose is insanely difficult if not impossible. Especially if your nucleophile is something as weak as aniline.

In any case, I think your nomenclature and spelling are out of whack. And I'm going to cry "Bullshit!" out loud if you say you don't have access to spell check.

Have a nice day.

Madancrazy, 1-flouro-3-bromo-5-chlorocyclooctane is not commercially available in if you are trying to convince anybody here that someone who can't distinguish aniline from benzylamine (even after it has been explained to him) is able to synthesize it, you are only deluding yourself and nobody else.
My compliments for the nickname you chose, though this latest post is nearly not as “mad and crazy” as the nonsense you are promoting in the acetic anhydride thread and other threads as well. Spreading nonsense and disinformation is doing no good to those who are beginners in chemistry and is highly antiscientific as well.

I know the 1-flouro-3-bromo-5-chlorocyclooctane is not available.
I mean is it easy connect two chemicals in a subtitution with several halogens
to a precise point of the chemical. Is the atomic weight, the atomic charge or
the binding between two chemicals significant.

Excuse me, the name is certainly 1-phenylamin-3-bromo-5-chlorocyclooctane
