Abstract Photocatalytic water splitting to hydrogen is a highly promising method meet the surging energy consumption globally through environmentally friendly means. As initial step before photocatalysis, harvesting photons from sunlight crucially important, thus making design of photosensitizers with visible even near‐infrared (NIR) absorptions get more and attentions. In past three years, organic donor/acceptor (D/A) heterojunctions extending 950 nm, have emerged as new star...
A DCP-mediated oxidative dual C–H selenation radical reaction of imidazoheterocycles with ethers or alkanes using selenium powder was developed.
A highly efficient method for the asymmetric synthesis of chiral quaternary carbon-containing homoallylic and homopropargylic amines under mild conditions was achieved with good yields high diastereoselectivities.
An efficient and convenient copper-catalyzed chalcogenation of imidazoheterocycles with sulfur/selenium powder coumarinyl triflates has been described. This procedure provides a wide range structurally diverse coumarinylthio-/coumarinylseleno-substituted in good yields functional group tolerance.
