Your question is Synthesizing Heteroleptic Iridium. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How would you synthesize a heteroleptic iridium(III) complex starting from iridium trichloride? Explain the ligand coordination steps and how you would control regioisomeric purity.
