Probing Electrocatalyst Design for Product Selectivity in CO2 Reduction
Advanced Science, EarlyView.Selective CO2 electroreduction is controlled by catalyst structure, dynamic surface reconstruction, adsorbate interactions, and reaction microenvironment. This review summarizes Cu‐ and non‐Cu‐based catalysts, single‐atom and molecular systems, degradation pathways, and operando/computational strategies for steering CO2RR toward hydrocarbons ...

Inadequacy of Continuum Solvation for Polar Reactions: Predicting the Mechanism of Carbonyl–Olefin Metathesis [PDF]
, 2022 In carbonyl–olefin metathesis, two π-bonds undergo a cycloaddition-cycloreversion process to form valuable alkenes from simple precursors. Although this synthetic methodology has advanced significantly, further improvements would be greatly facilitated ...

Olefin metathesis for chemical biology [PDF]
Current Opinion in Chemical Biology, 2008 Chemical biology relies on effective synthetic chemistry for building molecules to probe and modulate biological function. Olefin metathesis in organic solvents is a valuable addition to this armamentarium, and developments during the previous decade are enabling metathesis in aqueous solvents for the manipulation of biomolecules.

Phosphanyl Radicals From Bismuth‐Mediated Reactions and Sterically Encumbered Diphosphanes
Chemistry – A European Journal, EarlyView.Reactions of LiPR2 with BiCl3 selectively give diphosphanes R2P–PR2 in high yields, presumably via Bi─P homolysis. This includes challenging cases with bulky substituents R. Sterically encumbered diphosphanes release persistent phosphanyl radicals [PR2]• in thermally initiated equilibrium reactions.
