In this study a new methodology for doing simultaneous electrografting of two different organic films at each end of a gold substrate…
Aske S Donslund, Karoline T Neumann, Nicklas P Corneliussen, Ebbe K Grove, Domenique Herbstritt, Kim Daasbjerg, Troels Skrydstrup https://doi.org/10.1002/chem.201902206 Herein, we report a nickel‐catalyzed carbonylative coupling of α‐bromonitriles and alkylzinc reagents with near stoichiometric carbon monoxide to give β‐ketonitriles in good yields. The reaction is catalyzed by a readily available and stable nickel(II) pincer complex.…

Stoichiometric 13C-labeled carbon monoxide could be efficiently incorporated via Ni–C bond insertion to generate air stable and isolable cyclic Ni-acyl complexes. Upon subjection to…
Stefan Urth Nielsen, Mark Holm Olsen, Mikkel Skorkjær Kongsfelt, Steen Uttrup Pedersen, Kim Daasbjerg https://doi.org/10.1021/acsomega.9b01282 Leaching of chemicals from adhesion promoters is, in particular, problematic for the food, water, pharmaceutical, and MedTech industries where any chemical contamination is unacceptable. A solution to this issue is to employ covalently attached nanoscale polymer brushes as adhesive layers…
Xin-Ming Hu, Steen U Pedersen, Kim Daasbjerg https://doi.org/10.1016/j.coelec.2019.05.006 The thorough understanding of homogeneous catalysis has triggered intense research activities on the immobilization of molecular catalysts for the heterogeneous CO2 electroreduction. Herein, we discuss recent advances in the heterogeneous field with focus on the intrinsic effect coming from the catalyst structure and the extrinsic effect exerted by…

Dennis U Nielsen, Xin-Ming Hu, Kim Daasbjerg, Troels Skrydstrup https://doi.org/10.1038/s41929-018-0051-3 Carbon dioxide is ubiquitous and a vital molecule for maintaining life on our planet. However, the ever-increasing emission of anthropogenic CO2 into our atmosphere has provoked dramatic climate changes. In principle, CO2 could represent an important one-carbon building block for the chemical industry, yet its high thermodynamic…
