    • Bulky, electron-rich, renewable: analogues of Beller's phosphine for cross-couplings 

      van der Westhuizen, Danielle; Castro, Abril C; Hazari, Nilay; Gevorgyan, Ashot (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-30)
      In recent years, considerable progress has been made in the conversion of biomass into renewable chemicals, yet the range of value-added products that can be formed from biomass remains relatively small. Herein, we demonstrate that molecules available from biomass serve as viable starting materials for the synthesis of phosphine ligands, which can be used in homogeneous catalysis. Specifically, ...

    • Comparative study of CO2 insertion into pincer supported palladium alkyl and aryl complexes 

      Deziel, Anthony P.; Gahlawat, Sahil; Hazari, Nilay; Hopmann, Kathrin Helen; Mercado, Brandon Q. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-07-12)
      The insertion of CO2 into metal alkyl bonds is a crucial elementary step in transition metal-catalyzed processes for CO2 utilization. Here, we synthesize pincer-supported palladium complexes of the type (tBuPBP)Pd(alkyl) (tBuPBP = B(NCH2PtBu2)2C6H4−; alkyl = CH2CH3, CH2CH2CH3, CH2C6H5, and CH2-4-OMe-C6H4) and (tBuPBP)Pd(C6H5) and compare the rates of CO2 insertion into the palladium alkyl bonds to ...

    • Ligand and solvent effects on CO2 insertion into group 10 metal alkyl bonds 

      Deziel, Anthony P.; Espinosa, Matthew; Pavlovic, Ljiljana; Charboneau, David J.; Hazari, Nilay; Hopmann, Kathrin Helen; Mercado, Brandon Q. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-09)
      The insertion of carbon dioxide into metal element σ-bonds is an important elementary step in many catalytic reactions for carbon dioxide valorization. Here, the insertion of carbon dioxide into a family of group 10 alkyl complexes of the type (<sup>R</sup>PBP)M(CH<sub>3</sub>) (<sup>R</sup>PBP = B(NCH<sub>2</sub>PR<sub>2</sub>)<sub>2</sub>C<sub>6</sub>H<sub>4</sub><sup>−</sup>; R = Cy or <sup>t</sup>Bu; ...

    • Ni(I)–Alkyl Complexes Bearing Phenanthroline Ligands: Experimental Evidence for CO2 Insertion at Ni(I) Centers 

      Somerville, Rosie J.; Odena, Carlota; Obst, Marc; Hazari, Nilay; Hopmann, Kathrin Helen; Martin, Ruben (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-10)
      Although the catalytic carboxylation of unactivated alkyl electrophiles has reached remarkable levels of sophistication, the intermediacy of (phenanthroline)Ni(I)–alkyl species—complexes proposed in numerous Ni-catalyzed reductive cross-coupling reactions—has been subject to speculation. Herein we report the synthesis of such elusive (phenanthroline)Ni(I) species and their reactivity with CO<sub>2</sub>, ...

    • Organometallic Chemistry for Enabling Carbon Dioxide Utilization 

      Hazari, Nilay; Iwasawa, Nobuharu; Hopmann, Kathrin Helen (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-05-11)
      <p>In photosynthesis, carbon dioxide is used as the carbon source; indeed, most carbon atoms in the structure of a massive tree—the trunk, the branches, the leaves—originate from CO2. This insight has profound implications for chemical synthesis: complex molecular structures are built from something as simple and inert as CO<sub>2</sub>. Scientists have long been fascinated by this concept, and ...

    • Rational selection of co-catalysts for the deaminative hydrogenation of amides 

      Artús Suàrez, Lluís; Jayarathne, Upul; Balcells, David; Bernskoetter, Wesley H.; Hazari, Nilay; Jaraiz, Martin; Nova, Ainara (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-20)
      The catalytic hydrogenation of amides is an atom economical method to synthesize amines. Previously, it was serendipitously discovered that the combination of a secondary amide co-catalyst with (<sup>iPr</sup>PNP)Fe(H)(CO) (<sup>iPr</sup>PNP = N[CH<sub>2</sub>CH<sub>2</sub>(P<sup>i</sup>Pr<sub>2</sub>)]<sub>2</sub>−), results in a highly active base metal system for deaminative amide hydrogenation. ...
