Book Description
Ranging from hydrogenation to hydroamination, cycloadditions and nanoparticles, this first handbook to comprehensively cover the topic of iridium in synthesis discusses the important advances in iridium-catalyzed reactions, namely the use of iridium complexes in enantioselective catalysis. A must for organic, complex and catalytic chemists, as well as those working with/on organometallics.

Book Description
Reaction of the fragments {Ir(PEt3)n}+ with the monocarborane anion [closo-1-CB7H8]- causes an oxidative insertion to occur, and the iridium moiety to become a cluster vertex. This reaction provides two distinct, neutral, 9-vertex {IrCB7} products, depending on the ratio of iridium and phosphine reactants used. The iridium centers in these products have differing oxidation states, illustrating the exceptional ability of the smaller anionic monocarborane ligands to stabilize metals in higher oxidation states. Although salts of the 11-vertex anionic species [1,1,1-(CO)3-closo-1,2-FeCB9H10]- have resisted synthesis in the past, its analogue [1,1,1-(CO)3-2-Ph-closo-1,2-FeCB9H9]- has now been prepared. Moreover, two reactions demonstrating the derivative chemistry of this compound have been discovered. Previously, 10- and 12-vertex dicobalt monocarboranes were prepared and studied by treating monocarboranes with [Co2(CO)8]. This produced several poly-cobalt anions. New derivatives of these anions have been synthesized, using protocols developed since their discovery.

Book Description
Chemical oxidation by [FeCp2]PF6 afforded thermally unstable, paramagnetic Rh IV compounds, [Rh{ArNC(NR 2)NAr} 3]PF6, which were characterized by mass spectrometry and electronic absorption spectroscopy. Furthermore, two FeII complexes of tetradentate tripodal ligands, [Fe(L1)(OTf) 2] and [Fe(L2)(OTf) 2]; where L1 = N, N-bis(2-benzimidazolylmethyl)-N-(2-pyridylmethyl) amine and L2 = N, N-bis[(1-methylbenzimidazol-2-yl)methyl]-N-[(pyridin-2-yl)methyl] amine; were synthesized and characterized. The 1 H NMR spectra for [Fe(L1)(NCMe) 2](OTf) 2 and [Fe(L2)(NCMe) 2](OTf) 2 in CD3 CN solution at ambient temperature exhibit paramagnetically shifted peaks typical of high-spin FeII complexes, while variable-temperature 1 H NMR spectroscopy showed that the Fe center in [Fe(L1)(NCMe) 2](OTf) 2 is in a spin equilibrium and that in [Fe(L2)(NCMe) 2](OTf) 2 in the high-spin state (at 25° C). Highly reactive oxoiron(IV) complexes were obtained by reaction of the FeII complexes with an excess of m-CPBA at -40° C.
