WebApr 10, 2024 · The change in ring current for the cycle upon oxidation was clear from 1H NMR spectroscopy, as the protons of the thiophene and furan rings shifted downfield by nearly 6 ppm. This work highlights the potential of sequence control in furan-based macrocycles to tune electronic properties. WebSep 24, 2024 · The contents of thiophene and dibenzothiophene were determined in the linear temperature programmed mode in the range of 90–220°C using an internal standard. It was found that oxidation of the initial reagents (thiophene and dibenzothiophene) produced sulfuric acid and sulfone, respectively [ 24 ].
