Study notes
How did green chemistry redesign ibuprofen synthesis? Step 1: Old Boots route: 6 steps, stoichiometric reagents, much waste. Step 2: BHC route: 3 steps, catalytic (HF catalyst, recycled). Step 3: Atom economy jumped (~40% → ~80%); waste slashed. Step 4: Same drug, greener route — design beats cleanup!
