Synthesis and structural characterization of a binuclear iridium complex with bridging, bidentate N-heterocyclic carbene coordination of 2, 2 ':6 ', 2''-terpyridine
(Royal Society of Chemistry, 2009)
Thermal activation of terpyridine in the presence of an unsaturated Ir(III) fragment stabilized by a hydrotris(pyrazolyl) borate ligand gives rise to mononuclear complex 2 and binuclear 3, in which the polypyridine ...

A Diels–Alder Reaction Triggered by a [4 + 3] Metallacycloaddition
(American Chemical Society, 2015)
The TpMe2Ir(III) complex 1-OH2 (TpMe2 = hydrotris(3,5-dimethylpyrazolyl)borate), which contains a labile molecule of water and an iridium-bonded alkenyl moiety (−C(R)═C(R)–(R=CO2Me)) as part of a benzo-annulated five-membered ...

Investigations on the Coupling of Ethylene and Alkynes in Tp Me2 Ir Compounds: Water as an Effective Trapping Agent
(Wiley-VCH, 2007)
The reaction of the bis(ethylene) complex [TpMe2Ir(C2H4)2] (1) (TpMe: hydrotris(3,5-dimethylpyrazolyl)borate) with two equivalents of dimethyl acetylenedicarboxylate (DMAD) in CH2Cl2 at 25 °C gives the hydride–alkenyl ...

Functionalization of 3-Iridacyclopentenes
(Wiley, 2017)
Members of a series of iridacyclopentenes of composition [TpMe2Ir(k2-C,C-CH2CR′=CRCH2)(CO)] (TpMe2=hydrotris(3,5-dimethylpyrazolyl)borate; R=R′=H, 1; R=Me, R′=H, 2; R=R′=Me, 3) have been subjected to common organic chemistry ...

Reactivity of TpMe2-containing hydride-iridafurans with alkenes, alkynes, and H2
(American Chemical Society, 2014)
The TpMe2-containing hydride-iridafurans 2a,b (TpMe2 = hydrotris(3,5-dimethylpyrazolyl)borate) cleanly reacted with ethylene to give the bicyclic derivatives 6a,b. Formation of the latter complexes is a reversible process, ...

Formation of β-Metallanaphthalenes by the Coupling of a Benzo-Iridacyclopentadiene with Olefins
(American Chemical Society, 2015)
We have synthesized a new type of metallaaromatic complexes, namely the hydride-β-iridanaphthalenes TpMe2tiebar above startr(H)[C(CH2R′)-C6H4-o-C(R)═tiebar above endC(R)] (benzo-3-H,CH2R′), by reaction of the benzo-irida ...
