资源简介：
A nonheterocyclic bis(imino)aryl ligand with blocking
methyl substituents,
4,6-dimethyl-1,3-benzenediphenylimine (NCHN), has been synthesized.
Metalation via oxidative addition proceeds under mild conditions with
the Ir(I) reagent [Ir(CH2CH2)2(Cl)]2 to produce the Ir(III) product (NCN)Ir(CH2CH3)(Cl). Neutral nucleophiles such as water or triphenylphosphine
add readily to the vacant sixth coordination site. Protonation of
the ethyl group results in loss of ethane and formation of a dicationic
chloride-bridged (NCN)Ir dimer. Alternatively, the chloride ligand
can be abstracted from (NCN)Ir(CH2CH3)(Cl) to
provide access to various neutral and cationic species, including
(NCN)Ir(CH2CH3)(OAc) (OAc = acetate), [(NCN)Ir(CH2CH3)(bpy)][BF4] (bpy = 4,4′-bipyridine),
[(NCN)Ir(CH2CH3)(NCCH3)2][BF4], and [(NCN)Ir(CH2CH3)(OH2)2][BF4], which is water soluble.
