Title: Delepine with Et-Br
Post by: ChemicalSolution on December 24, 2001, 11:30:00 PM

Can some bee point me to a procedure for converting Et-Br to ethylamine using the Delipine reaction?  I realize this procedure works much better with NaI but Et-Br is all this bee has to work with.

Thanks--CH :)

Should also add.. SWIM wishes to convert Et-amine to tri ethyl amine.  Can this be done by refluxing Et-amine in IP-OH with an abundance of Et-Br like what would be done in the Bromosafrole reaction with NH3 only the higher amine is prefered.

Thanks!! CH :)

The Delepine probably only work well with iodides . So you'll have to reflux with NaI in acetone first.

And your idea will probably give you chiefly the quaternary salt.
Why don't you just buy triethylamine?

The Delepine works well with the bromides if NaI is added to the refluxing reaction mixture.
