Abstract

Figures for the Experimental Section (illustration of the setup utilized for in situ NMR experiments and continuous-flow reactions), control 1H NMR spectra of oxazolones 1, copies of 1H, 13C, and 19F NMR spectra for all new compounds 2 and 3, DP4 characterization of the μ-isomer, conversions (percent) of oxazolones 1 to give cyclobutene-bis(oxazolones) 2 from two consecutive reactions in microreactors, copies of the absorption (UV–vis) spectra of (Z)-oxazolones 1 and selected (E)-oxazolones, quenching experiments, LFP experiments, cyclic voltammograms, and DFT calculations (optimized geometries and tables with absolute and relative energies) (PDF). Geometries: coordinates of all species calculated in Figure 11, using different functionals, basis and solvents (ZIP).
