A combination of electrochemical, electrospray mass spectrometry, and 59 Co/ 77 Se NMR experiments confirms that the binuclear species, [Co 2 L 5 ] + , reacts with acetonitrile forming CoL 3 and [CoL 2 (CH 3 CN) 2 ] + . At the electrode surface, CoL 3 species generated by this ...
19F NMR (377 MHz, CDCl3)δ −115.97 (major), −116.73 (minor). The mixture of (Z)-2aa and (E)-2aa was obtained by a column chromatography separation of the crude mixture on silica gel (petroleum ether/ethyl acetate = 2:1), colorless oil, 100.0 mg, 96%. And, a ...
1H NMR spectra were recorded using a Bruker Avance NEO at 600 MHz in (CD3)2SO containing 0.03% tetramethylsilane (TMS). All spectra were referenced to the central peak of the residual resonance for (CD3)2SO at 2.50 ppm [41]. Chemical shifts (δ) are given in ppm and coupling ...
A combination of electrochemical, electrospary mass spectrometry, and ~(59)Co/~(77)Se NMR experiments confirms that the binuclear species, [Co_2L_5]~+, reacts with acetonitrile forming CoL_3 and [CoL_2(CH_3CN)_2]~+. At the electrode surface, CoL_3 species generated by this reaction...
