Well the NMR is back up and useable, although there are issues with locking and shimming, giving some peaks "shoulders" and occaisionally causing standard singlets to split. Thing needs some work. Anyways, the aforementioned 2c-b was analyzed post-bromination with trituration w/EtOAc as only purification method. Sample was prepared in D2O. Here are the peaks present on the spectra. SWIM has no scanner, but could always take a digicam picture of this if anybody
really wanted to see it.
Also the sample was very dilute; the solvent peak is huge compared to the 2c-b peaks, integration is a little wacky.
triplet, ~2.95ppm integration 1 (should be 2)
triplet, ~3.21ppm integration 1.5 (should be 2)
two identical singlets, 3.82ppm and 3.86ppm, overall integration 8.5 (should be 6)
broad peak from ~4.6ppm to ~5ppm centered at 4.80ppm (D2O solvent peak, integration in the 100's)
singlet (sharp) at ~7.02ppm, integration 1 (should be 1)
singlet (sharp) at ~7.32ppm, integration 1 (should be 1)
SWIM thinks this looks fine. There are no other peaks present, not even peaks for EtOAc to SWIM's surprise.
