About the Cover:An efficient visible-light induced nickel-catalyzed re-ductive Heck reaction of aryl halides and electron-defi-cient alkenes was developed by Liu, Zhao, Hu, Wang and Yuan on page 1691. Hantzsch ester was identified as a potent and very mild organic reductant to replace highly sensitive metal reductants in reductive Heck reaction. This reaction features mild reaction condition, broad substrate scope, and good functional group compatibility, thus providing an alternative approach for hydroarylation of alkenes. -
About the Cover:The photocatalytic systems for converting biomass derivatives into value-added chemicals are summaried by Tan, Shi, Zhang and Li on page 1523. It categorizes homogeneous catalytic mechanisms (LMCT, PCET, HAT, SET) and the catalytic materials of TiO2, CdS, etc. in heterogenous catalysis, emphasizing their roles in activating C—C and C—O bonds via radical-mediated pathways. This work provides a strategic foundation for the complete depolymerization of lignin, enabling the green and efficient production of high-value aromatic compounds from recalcitrant biomass feedstocks. -
About the Cover:The efficient transfer of nitrogen atom from ammonia and its equivalents to diverse organic compounds repre-sents the transfer of nitrogen from inorganic compounds to organic compounds resulting from the fixation of nitrogen gas. Therefore, it is of great value to develop the C—N bonding reaction involving ammonia and its equivalents by photocatalysis. The progress of light-catalyzed carbon-nitrogen bond-forming reactions invo-lving ammonia and its equivalents over recent years is summarized by Li, You, Li and Shu on page 1460. -
About the Cover:The recent progress in hydrogen atom transfer-mediated photocatalytic C(sp3)—H bond oxidation achieved over the past five years is summarized by Huang, Huang and Hu on page 1509. The reaction mechanisms are ana-lyzed and the substrate scope of these photocatalytic systems is evaluated. Furthermore, prospect for future research directions in the rapidly developing field of photochemical C—H bond oxidation is proposed.
