Zn/H_3O^+ Li in NH_3 KOh/ethanol NaNH_2/NH_3 Step 1: Step 2: Step 3:
Which reagent would you use to accomplish the following transformation? Select one: BH_3 middot THF, H_2O_2, H_2O, NaOH Hg(OAc)_2, H_3O^+, H_2O HCI (excess) CF_3CO_3H HO^-/H_2O
This one is NOT jkbf. Help please last try From the choices provided below, list the reagent(s) in order that will yield the transformation shown above. List your answers as a series of letters in the order the reagents are used (with no commas separating them). No more than four steps are required for this synthesis. Use the minimum number of steps possible. Reagents may be more than once is subsequent steps. Ex. "dop" corresponds to: NaCN NaOH PCC HlO_4...
