Abstract

We report the synthesis and structure of iridium(I) complexes with N,N′-disubstituted perimidine carbene ligands and halides or carboxylate ligands. Iodo-, chloro-, and acetate-Ir(carbene)(cod ) complexes were selectively prepared by changing the bases and silver salts. Intramolecular C−H bond activation to prepare a cyclometalated Ir(III) complex, (C ∧ C:) 2 Ir(OAc) (6), where C ∧ C: is a cyclometalated perimidine carbene ligand, was achieved using a carboxylate- ...
