In example 2, I believe, there is an extra carbon that shouldn’t be there. You use CH3-CH2-CH2-I and a cyclopentane directly attached to the CuLi, thus you should have 1-propyl-cyclopentane and not a 1-butyl-cyclopentane.
You are correct! I fixed the image. Thanks for spotting!
That is correct. C-2 attached to Cu is nucleophilic (partially negative) and C1 attached to Br is electrophilic (partially positive).
Oh, my mistake. Electronegativity (Cu) = 1,9 < Electronegativity (C) = 2,5. :-) Thx
Hi, please for explaining how is created bond C1 and C2 in Mechanism? C1 is (+) and Cu is (-) —> C2 is (+) I suppose. Thx. P.
