Base-promoted selective aryl carbon-bromine bond cleavage by Iridium(III) porphyrin for Iridium(III) porphyrin aryl synthesis: A metalloradical Ipso addition-elimination mechanism

K₂CO₃ was found to promote selective aryl carbon-bromine bond (Ar-Br) cleavage by a high-valent iridium(III) porphyrin carbonyl chloride (Ir^III(ttp)(CO)Cl, ttp = 5,10,15,20-tetra-p- tolylporphyrinato dianion) in benzene so
