2) Fill in the red box(es) with the missing reactant(s), reagent(s), product(s), solvent, and/or conditions and write a reasonable mechanism for the reaction. Not every box needs to be used and not every box necessarily corresponds to only a single species. If no reaction occurs OR no reagents exist to perform the reaction state, NOT POSSIBLE AND explain why. O, CH,Cl, -78 C A. 3) Explain how and why the reaction below results in the observed regiochemistry and/or stereochemistry. going - . & A A
