- Using what we have learned in CHEM 2310 and up through class on 1/31, propose a series of reaction steps to achieve the transformation below. Be sure to show all reagents and intermediates for full credit. You do not need to draw mechanism arrows, but you do need to include charges where appropriate. If you do not put your group name, you will get half credit at most. ?
