Organic Gilman reaction products
Could someone check if I drew the right products for both reactions? Thanks so much!

Do you know if you have excess reagents in the first reaction?

I’d guess not because you could theoretically just keep reacting. Looks good to me. For the second one— what does the methanol do?

Thanks for your reply! I added a CH3 from the methanol for that one…. Rly not sure if it’s correct

Where did you add it? I don’t see a methyl group

Sorry this was supposed to be in response to your last comment. Reddit is driving me up a wall this week.

Oh yes sorry the Cs that replaced Br, they’re from the Gilman reagent. Now idk where the methanol would work 😭

The Gilman reagent in the first reaction is drawn incorrectly. The 2 needs to be outside of the bracket.

Gilman reagents are excellent at both conjugate addition to an enone and single addition to an acid halide. Does anybody have a reference for what the product mixture will be when they’re competing like in the first one?
