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.
