Redox‐Active Frustrated Lewis Pair‐Mediated B─H Bond Activation: From Proton Transfer to THF Ring Opening

ChemistryEurope, EarlyView.
Carbene‐stabilized dithiolene zwitterion, as a redox‐active frustrated Lewis pair, can mediate the B─H bond activation of catecholborane via hydride‐coupled reverse electron transfer processes. This discovery represents the first experimental evidence of the FLP‐mediated B─H activation via net proton transfer.

Hydrogen Bonding is Key Factor in Reversible NH3 Uptake Causing Vapochromic and Magnetochemical Switching in Ni(II) Paddlewheel Complexes

ChemistryEurope, EarlyView.
Nickel complexes showing reversible vapochromic and spin crossover behaviors upon coordination and release of NH3 were synthesized. They bear bidentate pyridazine ligands, which allows for formation of hydrogen bonds between NH3 and the ligand in the second coordination sphere.

Advances in Parahydrogen‐Induced Polarization for Nuclear Magnetic Resonance of Peptides, Proteins, and Biopolymers

ChemistryEurope, EarlyView.
Hyperpolarization by parahydrogen‐induced polarization enhances the sensitivity of nuclear magnetic resonance spectroscopy of amino acids, peptides, mini‐proteins, and biopolymers using nonnatural amino acids with unsaturated side chains up to three orders of magnitude.
