Synthesis of new heteroscorpionate iridium(I) and iridium(III) complexes.
The reactivity of different heteroscorpionate ligands based on bis(pyrazol-1-yl)methane, with different iridium-(i) and -(iii) precursors is reported. The reaction of the heteroscorpionate lithium salts "Li(bdmpza)", [bdmpza = bis(3,5-dimethylpyrazol-1-yl)acetate], "Li(bdmpzdta)" [bdmpzdta = bis(3,5-dimethylpyrazol-1-yl)dithioacetate] and "Li(S)-mbpam" [(S)-mbpam = (S)-(-)-N-α-methylbenzyl-2,2-...
متن کاملIridium-Catalyzed Arylative Cyclization of Alkynones by 1,4-Iridium Migration**
1,4-Metal migrations enable the remote functionalization of C-H bonds, and have been utilized in a wide variety of valuable synthetic methods. The vast majority of existing examples involve the 1,4-migration of palladium or rhodium. Herein, the stereoselective synthesis of complex polycycles by the iridium-catalyzed arylative cyclization of alkynones with arylboronic acids is described. To our ...
متن کاملSynthesis and Characterization of Aminocarboxylato Iridium(III) Complexes
Aminocarboxylic acids, such as 2-aminobenzoic acid, react easily with [Ir(COD)(PMe3)3]Cl, (COD=1,5-cyclooctadiene), in THF to produce hydridoaminocarboxylato iridium(III) complexes in high yields. These octahedral complexes are formed via oxidative addition reaction of the O-H bond of the carboxylic group with the central metal. The starting iridium(I) complex losses t...
متن کاملThe dual role of borohydride depending on reaction temperature: synthesis of iridium and iridium oxide.
Temperature dependent reaction products are observed when borohydride is present in aqueous solutions containing Ir(3+). At temperatures of 40 °C and above, metallic iridium is formed while under ambient conditions of 25 °C, borohydride results in an alkaline environment that helps in hydrolyzing the precursor to form IrO2. The Ir foams and IrO2 are subsequently used to study their catalytic pr...
متن کاملLaser spectroscopy of iridium monoboride.
High resolution laser induced fluorescence spectrum of IrB in the spectral region between 545 and 610 nm has been recorded and analyzed. Reacting laser-ablated iridium atoms with 1% B(2)H(6) seeded in argon produced the IrB molecule. This is the first experimental observation of the IrB molecule. Four vibronic transition bands, (v,0) with v=0-3 of an electronic transition system, have been obse...
