are conveniently synthesized from polyolesters and azaheterocyclic salts under solventless conditions. In particular, paraquat-like derivatives showed comparable herbicidal activity toward several common weeds. Mechanistic studies suggest that polyesters likely underwent partial hydrolysis and neighboring group participating dehydration under the action of acidic salt to generate five-membered ring
We have newly prepared and characterized a series of the azaferrocene-based PNP-type pincer ligands and the corresponding molybdenum, chromium, and iron complexes. The stoichiometric and catalytic reactivity of molybdenum-dinitrogen complexes toward nitrogen fixation has been investigated in details.

applying proton-coupledelectrontransfer (PCET) reagents in reductive electro- and photocatalysis requires strategies that mitigate the competing hydrogen evolution reaction. Photoexcitation of a PCET donor to a charge-separated state (CSS) can produce a powerful H-atom donor capable of being electrochemically recycled at a comparatively anodic potential corresponding to its ground state. However
