Photoreductive Dissolution of Iron Oxides Trapped in Ice and Its Environmental Implications [PDF]

, 2010
The availability of iron has been thought to be a main limiting factor for the productivity of phytoplankton and related with the uptake of atmospheric CO_2 and algal blooms in fresh and sea waters. In this work, the formation of bioavailable iron (Fe(II)

Chan–Lam Cross‐Coupling With Alkylboron Reagents: From Transmetallation to Radical Pathways

European Journal of Organic Chemistry, EarlyView.
Alkylative Chan–Lam coupling overcomes intrinsic transmetallation limitations of alkylboron reagents by engaging radical pathways. Recent advances reveal how radical and radical–polar crossover mechanisms enable mild C(sp3)—heteroatom bond formation. This minireview highlights key mechanistic insights and emerging strategies that transform alkylboron ...

Highly Active CH Bond Borylation of Aromatics With Pyridine as Convenient, Low-Cost Ligand Under Iridium Catalysis. [PDF]

ChemSusChem
The highly atom‐economy iridium‐catalyzed CH bond borylation of aromatics has been achieved utilizing simple and trivial pyridine as the ligand, which is 2–3 orders of magnitude cheaper than the current state‐of‐the‐art ligands, thus significantly reducing both the E‐factor and the carbon footprint associated with tedious and waste‐generating ligand ...
