antonymnz asked:

so I just looked over my old notes and we never covered the mechanism of organometallics cause they were beyond the scope of the class so it was just a given that you had to use two equivalents but wikipedia offers some insight that may be helpful, just look up grignard reaction.

I started looking it up, because I was curious. And I found this picture…

So I guess the 2nd equivalent of BrMg-R provides stability as one the R groups comes off the first equivalent?

Idk, it’s like a transfer.

Yeah, it kinda reminds me of a diels-alder reaction but w/o the ring formation

I thought the answer should have been b … but the answer key said it was d.

I’ve been out of Organic Chemistry too long, so I have no clue, but chemistry savvy followers could you help out my friend? :)
Thanks!

When using Grignard’s (R-MgBr) you need at least 2 equivalents to carry out the reaction and get B, otherwise it will not work.
