Organocopper 1,4 addition
« on: July 14, 2020, 05:14:45 AM »
Hi!

I've a little doubt about this mecanism regarding 1,4 addition:



After the 1,4 addition I should have :
Cu+
MgBrCl
...and the carbonyl compound

And the counter ion of the negative charged ocygen should be the charged Cu+

Why  does  happen  the reaction:
Cu+ + MgBrCl ----> MgBr+ + CuCl

And MgBr+ is the  oxygen counter ion instead of Cu+??


Thankss!!!
