文摘

The synthesis of 3,4-dimethylphosphaferrocene (1) complexes of rhodium ([Rh(1)₃Cl], 2, and [Rh(1)₄][BF₄], 3) and iridium ([Ir(1)₃(COD)][BF₄], 4) arereported. An X-ray crystal structure analysis of thehomoleptic derivative 3 reveals that ligands arrangearound the rhodium center without apparent stericcongestion. Complex 4, which was also structurallycharacterized, adopts a trigonal bipyramid geometry inthe solid state. The reaction of 4 with H₂ under pressureyields the [Ir(1)₄H₂]⁺ complex.
