CO2‐to‐Cyclic Carbonate Transformation at Ambient Pressure Using a Mechanochemically Prepared Ti(III) Catalyst

Advanced Synthesis &Catalysis, EarlyView.
A Ti(III) complex synthesized mechanochemically catalyzes the cycloaddition of CO2 (1 bar) with terminal, internal, and trisubstituted epoxides. Mechanistic studies by density functional theory calculations reveal that the superior activity of Ti(III) compared to Ti(IV) arises from its lower oxophilicity, facilitating CO2 insertion into Ti–O bonds, as ...

Biobased Ligands Enable Catalysis with Base Metals

Advanced Synthesis &Catalysis, EarlyView.
Biobased ligands unlock versatile catalytic transformations, including Cu‐catalyzed hydroboration of olefins and borylation of alkyl halides, Fe‐catalyzed ketone hydrogenation, and Ni‐catalyzed terminal alkyne dimerization. First‐row transition metal catalysis has already reshaped organic synthesis, offering more abundant and cost‐effective ...

Bio‐Inspired Polymer Nanoreactor: Integrating Hemin Coordination and Micellar Confinement for Catalysis in Water

Advanced Sustainable Systems, EarlyView.
This study develops an amphiphilic copolymer nanocarrier (P(His‐r‐Sty)‐b‐PDMAA) for aqueous hemin catalysis, enabling efficient styrene cyclopropanation (94.4% yield, 0.3 mol% hemin) with excellent recyclability (>90% activity after 4 cycles), overcoming solubility and microenvironment challenges.
