Instead, the GC–MS and 1H NMR analysis of the reaction mixture showed the existence of cyclohexyl radical trapped by TEMPO (Supplementary Figs 66,67). Next, kinetic isotopic effect studies with separate kinetic experiments were performed to gain insights into the rate- determining step for this ...

Materials and methods, experimental procedures, useful information, mechanistic studies, 1H NMR spectra, 13C NMR spectra and mass spectrometry data are available in the Supplementary Information. Crystallographic data for compounds 2, 31, 33, 44, 64 and 69 have been deposited with the Cambridge Crys...
Proton NMR spectra were obtained on a Bruker Advance Neo 500 MHz spectrometer. LC/MS were obtained on an Agilent ion-trap LC/MS system. Chromatography was performed using an ISCO CombiFlash® Rf+ instrument. The synthesis of compound 2 has been previously reported.26 Download: Download high-...
