We demonstrated that such metallate is the real catalytic active species for the cycloaddition of CO2 to the epoxides, formed from the insitu reaction of the related [OSSO]‐Fe(III) neutral complexes and tetrabutylammonium bromide. The metallate complex was used as a single component catalyst ...

The selection of the catalyst is central to being able to control features and to better understand microstructures of polymers. New single-site metal alkoxide catalysts allow chemists to prepare regio/stereo regular polymers or copolymers that meet increasingly demanding performance requirements. These ca...

rutheniump>Well-defined ruthenium(II) phosphinous acid (PA) complexes enabled chemo-, site-, and diastereoselective CH functionalization of arenes and alkenes with ample scope. The outstanding catalytic activity was reflected by catalyst loadings as low as 0.75mol%, and the most step-economical ...

importantly, extremely high activity, with the highest TOF (6.8 × 105 h−1) so far reported for the reaction. The high activity can be related to the single-site metal dispersion and unhindered open metal environments enabled by the structure of the supporting MOF. The catalyst is...
The catalysis proceeds through two stepwise excited-state redox events—atypical of the currently known homogeneous photocatalysis—and features the storage of multiple redox equivalents on a dirhodium catalyst enabled by low-energy light. This is a preview of subscription content, access via your ...
