Electrochemical Thermospray Mass Spectrometry
Hambitzer, Guenther,Heitbaum, Joachim
, p. 1067 - 1070 (1986)
Thermospray ionization combined with a quadrupole mass spectrometer was used on line to detect electrochemically generated products directly from solution.To do so, an electrochemical cell was constructed and connected with the mass spectrometer in such a way that the electrolyte was forced by pressure from the working electrode into the heated capillary tube of the thermospray system.The fast response achieved allowed analysis to be performed in parallel with a cyclic voltammetry curve.The utility of the method is demonstrated by means of the electrooxidation of N, N -dimethylaniline in an aqueous medium.The potential-dependent formation of dimers and trimers is shown.

In this study, a heterogeneous rhodium-catalyzed oxidative homocoupling reaction of anilines utilizing molecular oxygen as the sole oxidant is reported. Employing a commercially available and recyclable Rh/C catalyst enabled the oxidative dimerization of various anilines, including N,N-disubstituted and N-monosubstituted anilines, as well as diarylamines, triarylamines, and carbazoles. Additionally, the catalytic protocol was extended to the ortho-ortho coupling of anilines, affording 2,2′-diaminobiphenyls with high regioselectivity. Notably, the developed approach provides rapid access to diversely functionalized benzidines and diaminobiphenyls in an operationally simple, practical, and environmentally friendly manner.
Electrochemical dehydrogenative cross-coupling of two anilines: Facile synthesis of unsymmetrical biaryls

A new, general ortho/para-selective anodic dehydrogenative cross-coupling of two aryl amines, naphthalen-2-amine derivatives and anilines, is described. This electrochemical protocol assembles a wide range of unsymmetrical biaryls in good to excellent yields under mild, additional-metal-catalyst-free, oxidant-free conditions with excellent selectivity, broad substrate scope, and wide functional group tolerance. This electrochemical technology is highlighted with facile incorporation of important pharmacophores into the resulting biaryls, and is applicable to the homocoupling of anilines for producing symmetrical biaryls.
