Hi everyone,
When practicing problem for conjugate addition, I've met one problem:
What is the product of this compound when reacted with i-PrMgCl, CuSPh:
Since there is CuSPh, the transmetalation occurs to form i-PrCu which is a soft nucleophile, the conjugate addition occurs. My product is:
But the product in the solution is:
So, can anyone here let me know whether I'm correct or the book is correct and if I'm wrong, where am I wrong ?
Thank you
