Investigation of the Reactivity of NHC-Boranes Complexes
N-heterocyclic carbenes boranes (NHC-Boranes) complexes are novel structures whose reactivity —especially organic— has not been explored. Our goal was to investigate the influence of the NHC complexation on the reactivity at the boron atom.

Substituent Effects in NHC-Boranes: Reactivity Switch in the Nucleophilic Fluorination of NHC- Boranes.
Synlett
2013
Substituents on the boron atom of NHC–boranes direct the reactivity of the ligated boreniums obtained through hydride abstraction. Depending on the electronics of the substituent, the reaction is selectively steered toward either B-substitution or Lewis base exchange.

January 31, 2013
By using the Telospot assay, 27 different extracts of cyanobacteria were evaluated for telomerase inhibition. All extracts showed varying, but significant activity. We selected Microcystis aeruguinosa PCC 7806 to identify the active compound and a bioassay guided fractionation led us to isolate mixtures of sulfoquinovosyl diacylglycerols (SQDGs), which were identified by 2D NMR and MS/MS...more
Synthesis and Reactions of N-Heterocyclic Carbene Boranes.
Angew. Chem. Int. Ed.
September 7, 2011
Boranes are widely used Lewis acids and N-heterocyclic carbenes (NHCs) are popular Lewis bases, so it is remarkable how little was known about their derived complexes until recently. NHC-boranes are typically readily accessible and many are so stable that they can be treated like organic compounds rather than complexes. They do not exhibit “borane chemistry”, but instead are proving to have a rich...more
Electron Paramagnetic Resonance and Computational Studies of Radicals derived from Boron-Substituted N-Heterocyclic Carbene Boranes.
J. Am. Chem. Soc.
May 28, 2011
Fifteen second-generation NHC-ligated boranes with aryl and alkyl substituents on boron were prepared, and their radical chemistry was explored by electron paramagnetic resonance (EPR) spectroscopy and calculations. Hydrogen atom abstraction from NHC–BH2Ar groups produced boryl radicals akin to diphenylmethyl with spin extensively delocalized across the NHC, BH, and aryl units. All of the NHC–B·...more Curie

J. Org. Chem.
September 14, 2010
A versatile new method for the preparation of NHC boranes starting from two stable, readily available reactants―an heterocyclic salt and an amine or phosphine−borane―is reported. It uses a Lewis base exchange at boron and provides easy access to new NHC boranes, in particular B-substituted borane ones.Curie
N-Heterocyclic Carbenes−Borane Complexes: A New Class of Initiators for Radical Photopolymerization.
Macromolecules
February 8, 2010
Newly discovered N-heterocyclic carbene-boryl radicals (NHC-BH2•) derived from readily available N-heterocyclic carbene−boranes are found to be efficient initiators for acrylate photopolymerization. Laser flash photolysis (LFP) experiments were used to generate three carbene-boryl radicals, which were characterized by their transient absorption spectra with the aid of DFT calculations. Rate...more
EPR Studies of the Generation, Structure, and Reactivity of N-Heterocyclic Carbene Borane Radicals.
J. Am. Chem. Soc
January 27, 2010
N-Heterocyclic carbene boranes (NHC−boranes) are a new “clean” class of reagents suitable for reductive radical chain transformations. Their structures are well suited for their reactivity to be tuned by inclusion of different NHC ring units and by appropriate placement of diverse substituents. EPR spectra were obtained for the boron-centered radicals generated on removal of one of the BH3...more
Ionic and Organometallic Reductions with N-Heterocyclic Carbene Boranes.
Chem. Eur. J.
November 4, 2009
N-Heterocyclic carbene–borane complexes such as depicted are neutral, organic soluble analogues of borohydride anions with a weak hydridic character, compatible with organometallic catalysis. They are applicable for surgical reductions in complex, multifunctional molecules.
Suzuki-Miyaura Coupling of NHC-Boranes: A New Addition to the C-C bond Toolbox
Org. Lett.
October 2, 2009
Complexes of triaryl- and trialkylboranes with N-heterocyclic carbenes (NHCs) participate in Suzuki−Miyaura cross-coupling reactions and provide coupled products in good yields under base-free conditions. The reaction can be applied to Csp2−Csp2 and Csp2−Csp3 carbon−carbon bond formation with triflates, iodides, bromides, and chlorides. These results enrich the utility of NHC−borane complexes,...more
Complexes of Borane and N-Heterocyclic Carbenes: A New Class of Radical Hydrogen Atom Donor
J. Am. Chem. Soc.
July 9, 2008
Calculations suggest that complexes of borane with N-heterocyclic carbenes (NHC) have B−H bond dissocation energies more then 20 kcal/mol less than free borane, diborane, borane−THF, and related complexes. Values are in the range of popular radical hydrogen atom donors like tin hydrides (70−80 kcal/mol). The resulting prediction that NHC borane complexes could be used as radical hydrogen atom...more
