Concurrent activation and conversion of N2 CO2 are significance yet face numerous obstacles due to the large dissociation energies N≡N C═O bonds. Utilizing a specifically developed reflectron time-of-flight mass spectrometer, we investigated dual mediated by copper silver ions under ambient conditions. Isotope experiments identified that both can be effectively activated generate N–O coupling product (NO+), especially in presence ions, NO+ attains maximum intensity with an N2/CO2 ratio 1:2, which validates three-molecule reaction mechanism, namely, + 2CO2 → 2NO 2CO. Through detailed analyses thermo-dynamics dynamics, illustrate Cu+-catalyzed mechanism for coupling, validating simply plasma-assisted single-ion catalysis.

In this work, a tunable reaction of metal acyl nitrene with ylides is reported for the divergent synthesis enamides and α,α-dicarbonyl phosphorus ylides. The featured mild conditions, good efficiency, broad generality. particular, resulting could be structurally elaborated into potential useful scaffolds. Mechanism investigation suggests that formation was ascribed to nucleophilic substitution ferric sulfur It believed represents an initial example preparing from iron-catalyzed transfer.
