NB! The anionic ligand 2 was synthesized through deprotonation of a planar, formally zwitterionic diazadiborine precursor, isolated as a lithium salt, and structurally characterized. According to experimental evidence and theoretical calculations, 2 can be considered as an intermediate between two classical classes of ligands: N-heterocyclic carbenes 1 and terphenyls 3.

Isolation of Free Phenylide-like Carbanions with N-Heterocyclic Carbene Frameworks

Krahulic, Kelly; Tuononen, Heikki; Parvez, Masood; Roesler, Roland (ACS, 2009)

A series of 1,3-bis(2,6-diisopropylphenyl)-5-methyl-1,3-diaza-4,6-diborabenzenes with methyl, phenyl, and dimethylamino substituents on the ring boron atoms were prepared using the cyclocondensation reaction between ...
The influence of electron delocalization upon the stability and structure of potential N-heterocyclic carbene precursors with 1,3-diaryl-imidazolidine-4,5-dione skeletons

Hobbs, Matthew; Forster, Taryn; Borau-Garcia, Javier; Knapp, Chrissy; Tuononen, Heikki; Roesler, Roland (RSC, 2010)

Targeting N-heterocyclic carbenes (NHCs) with increased π-acceptor character featuring N-fluorophenyl substituents, the molecular 2-chloro-1,3-bis(fluorophenyl)imidazolidine-4,5-diones (1a–c) were isolated from the ...
N-Heterocyclic Carbenes with Inorganic Backbones: Electronic Structures and Ligand Properties

Kausamo, Anna; Tuononen, Heikki; Krahulic, Kelly; Roesler, Roland (ACS, 2008)

The electronic structures of known N-heterocyclic carbenes (NHCs) with boron, nitrogen, and phosphorus backbones are examined using quantum chemical methods and compared to the experimental results and to the computational ...
Extending the Series: Synthesis and Characterization of a Dicationic N-Heterocyclic Selenium Carbene Analogue

Dutton, Jason; Tuononen, Heikki; Jennings, Michael; Ragogna, Paul (ACS, 2006)

The room-temperature reaction between the Dipp2DAB ligand, SnCl2, and SeCl4 results in the quantitative formation of a dicationic N-heterocyclic “carbenoid”. This represents the first example of a chalcogenium dication ...
Ammonia Activation by a Nickel NCN-Pincer Complex featuring a Non-Innocent N-Heterocyclic Carbene: Ammine and Amido Complexes in Equilibrium

Brown, Rudy M.; Garcia, Javier Borau; Valjus, Juuso; Roberts, Christopher; Tuononen, Heikki; Parvez, Masood; Roesler, Roland (Wiley - VCH Verlag GmbH & Co. KGaA, 2015)

A Ni0-NCN pincer complex featuring a six-membered N-heterocyclic carbene (NHC) central platform and amidine pendant arms was synthesized by deprotonation of its NiII precursor. It retained chloride in the square-planar ...
