Synthesis and Reactivity of Phosphirane Ligands and the Structural Characterization of Cp*IrCl2(tert-butylphosphirane)
摘要:
New and stable phosphiranes, tert-butylphosphirane and xylylphosphirane, were prepared. tert-Butylphosphirane is stable to polymerization in the presence of electrophiles. It was reacted with bis((mu-chloro)chloro(pentamethylcyclopentadienyl)iridium) to prepare (tert-butylphosphirane)dichloro(pentamethylcyclopentadienyl)iridium, which was characterized by X-ray diffraction, tert-Butylphosphirane was also reacted with pentacarbonyl(tetrahydrofuran)tungsten and borane to form (tert-butylphosphirane)pentacarbonyltungsten and the first phosphirane-borane adduct, respectively.
The present invention provides methods of administering Factor IX; methods of administering chimeric and hybrid polypeptides comprising Factor IX; polynucleotides encoding such chimeric and hybrid polypeptides; cells comprising such polynucleotides; and methods of producing such chimeric and hybrid polypeptides using such cells.
