Coupling of Aromatic Aldehydes with CO2Me-Substituted TpMe2Ir(III) Metallacyclopentadienes
(American Chemical Society, 2012)
The fully CO2Me substituted aquo-iridacyclopentadiene 1 reacts with a variety of aromatic aldehydes, at 90–120 °C, with the formation of bicyclic Fischer-type carbenes, generated by the transfer of the aldehydic H atom to ...

Synthesis, structure and reactivity of Pd and Ir complexes based on new lutidine-derived NHC/phosphine mixed pincer ligands
(Royal Society of Chemistry, 2016)
Coordination studies of new lutidine-derived hybrid NHC/phosphine ligands (CNP) to Pd and Ir have been performed. Treatment of the square-planar [Pd(CNP)Cl](AgCl2) complex 2a with KHMDS produces the selective deprotonation ...

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 ...

Catalytic amine-borane dehydrogenation by a PCP-pincer palladium complex: A combined experimental and DFT analysis of the reaction mechanism
(Royal Society of Chemistry (Great Britain), 2013)
Catalytic dehydrogenation of ammonia-borane (NH3·BH 3, AB) and dimethylamine borane (NHMe2·BH 3, DMAB) by the PdII complex [(tBuPCP)Pd(H 2O)]PF6 [tBuPCP = 2,6-C6H 3(CH2PtBu2)2] leads to oligomerization and formation of ...

Hydroboration of carbon dioxide with catechol- and pinacolborane using an Ir–CNP* pincer complex. Water influence on the catalytic activity
(Royal Society of Chemistry, 2018)
Iridium complexes based on deprotonated lutidine-derived CNP* pincers 2a/2b selectively catalyzed the hydroboration of CO2 under mild conditions (1–2 bar CO2, 30 °C) to methoxyborane using HBcat (TOF up to 56 h−1 ) and ...

Hydrogenation of an iridium-coordinated imidazol-2-ylidene ligand fragment
(Royal Society of Chemistry, 2018)
An iridium complex featuring a metalated lutidine-derived CNP ligand reacts with KOt Bu to yield a dimeric species with the two metal centers bound to the opposite ligands through the CHN arms. Furthermore, reaction ...

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 ...
