1-tris(diphenylphosphinomethyl)ethane; X = Cl, Br) yields an insoluble product believed to be oligomeric [Ir(triphos)X3]n with bridging triphos and halide ligands. Refluxing pyridine (py) dissolves the insoluble photoproducts ultimately yielding the dangling triphos complexes mer-Ir(κ2-triphos)(py)X3. Oxidation of the P center of the dangling arm of Ir(κ2-triphos)(py)Cl3 yields mer-Ir(κ2-P,P-triphosO)(py)Cl3 (triphosO
Ir(triphos)X 3(triphos = 1,1,1-tris(diphenylphosphinomethyl)ethane; X = Cl,Br)的光解产生不溶性产物,该产物被认为是低聚的[Ir(triphos)X 3 ] n,具有三桥联和卤化物
