The exceptional proton affinity of these compounds is partly due to the formation of a new bond between the C atom of CN and the atom with the electron pair upon protonation of the N atom of the CN group. The c
Protonation mediated interchange between mono- and bidentate coordination of N-benzoyl-N′,N′-dialkylthioureas: crystal structure of trans-bis(N-benzoyl-N′,N′-di(n-butyl)thiourea-S)-diiodoplatinum(II) This paper is dedicated to Professor Dr Lothar Bayer, on the occasion of his 60th ...
The protonation equilibria of four substituted N-methylbenzenesulfonamides, X-MBS: X = 4-MeO (3a), 4-Me (3b), 4-Cl (3c) and 4-NO2 (3d), in aqueous sulfuric acid were studied at 25 °C by UV–vis spectroscopy. As expected, the values for the acidity constants are highly dependent...

The electrochemical studies of these alkoxy-substituted imines have indicated a better p-type behavior after protonation induced by the capability of the protonated form to easily oxidize in acetonitrile and to generate the native molecules. The environmental polarity has also had impact on the doping...
has been tested by measuring the enthalpy of protonation of tris(hydroxymethyl)-aminomethane. Before each experiment, a full dynamic calibration was performed. Multiple titrations were conducted with solutions of different concentrations of H 3 L. For each titration, n additions were made (usually n...
