NMR spectra were acquired at the MIT Department of Chemistry Instrumentation Facility (DCIF) on Bruker Avance-III HD Nanobay (400 MHz), Bruker Avance Neo (400 and 500 MHz), and JEOL ECZ (500 MHz) spectrometers at room temperature. Referencing was performed during data acquisition by referencing against the deuterated solvent used. Quantitative NMR were performed with 4,4’-difluoropbenzophenone as a fluorine standard. NMR spectral data were reported as detailed below: chemical shift (ppm), integration, peak shape (m = multiplet). Mnova (https://mestrelab.com/) is necessary to open the processed files (.mnova) and raw data files with the .jdf extension. All other raw data files may be opened with any NMR processing software.
