摘要: We report the first synthesis of π-bonded rhodio and iridio-o-benzoquinones [Cp*M(o-benzoquinone)] (M = Rh (3a); M Ir (3b)) following a novel synthetic procedure. These compounds were fully characterized by spectroscopic methods; in particular X-ray molecular structure 3b was determined. Compounds 3a,b used as chelating organometallic linkers for design new family chiral octahedral bimetallic complexes, 4−9. The [(bpy)2Ru(3b)][OTf]2 (5) is presented shows that linker ruthenium center. In particular, carbocycle adopts η4-quinone form, where Cp*Ir also bonded to only four carbons. Further our strategy assemblies with successfully achieved. hold promise properties relative those made from organic bidentate ligands.
