Alkyne Synthesis from Dihalides
« on: December 02, 2012, 05:43:32 PM »
Working on alkyne synthesis from dihalides:

Why when you have (CH3)2CHCH(Br)CH(Br)CH3 reacted with -NH2 do you produce the alkyne (CH3)2CHC≡CCH3 but not (CH3)2C=C=CCH3. It seems that this outcome would be possible and have a higher reaction rate than the previous product. Does Zaitsev's rule apply?

Thanks  ;D

I don't think you can synthesise allenes by this method. Zaitsev's rule was meant to be broken and can only help you in a few cases. So the acetylene will be the product.
