The Mode of Protonation of Amides [PDF]

, 1958
The relative basicities of oxygen versus nitrogen in amides is a problem which has not been satisfactorily resolved. However, it might be anticipated from considerations of resonance and structural parameters that in strongly acidic solutions the proton ...

NiH-catalyzed asymmetric hydroalkynylation of α,β-unsaturated amides

Green Synthesis and Catalysis, 2022
An enantioselective NiH-catalyzed hydroalkynylation of α,β-unsaturated amides is reported. A wide range of α,β-unsaturated amides and bromoalkynes are suitable substrates for this reaction, which proceeds under mild conditions, allowing access to a ...

Detection of atmospheric gaseous amines and amides by a high-resolution time-of-flight chemical ionization mass spectrometer with protonated ethanol reagent ions [PDF]

Atmospheric Chemistry and Physics, 2016
Amines and amides are important atmospheric organic-nitrogen compounds but high time resolution, highly sensitive, and simultaneous ambient measurements of these species are rather sparse.
