Advanced Science, EarlyView.We present a mechanochemical, radical‐mediated hydroselenation of alkenes under ambient conditions. This method modularly generates alkyl selenyl radicals from elemental selenium and alkyl (pseudo)halides, utilizing PhSiH3 and H2O as hydrogen atom donors, with the water likely originating from the air and/or trace water present in the reagents ...

Photoinitiated oxidative addition of CF3I to gold(I) and facile aryl-CF3 reductive elimination. [PDF]
, 2014 Herein we report the mechanism of oxidative addition of CF3I to Au(I), and remarkably fast Caryl-CF3 bond reductive elimination from Au(III) cations. CF3I undergoes a fast, formal oxidative addition to R3PAuR (R = Cy, R = 3,5-F2-C6H4, 4-F-C6H4, C6H5, 4 ...

Tuned Oxidation Potential of Continuous Defective Photocatalyst for Selective Biomass Conversion
Advanced Science, EarlyView.This work develops a wavelength‐controlled photocatalytic strategy that utilizes defect‐state excitation to modulate oxidative capability for biomass selective conversion. By tuning the photooxidation potential to match substrate reactivity, the system suppresses overoxidation and enables the selective formation of value‐added products, providing a ...
