NMR Spectroscopy Protocol for Reagents

Example 1

Reagents and starting materials were obtained by commercial sources unless otherwise stated and were used without purification.

Proton and carbon NMR spectra (as applies to Example 1) were acquired on either of a Bruker Biospin DRX 400 MHz FTNMR spectrometer operating at a ¹H and ¹³C resonant frequency of 400 and 100 MHz respectively, or on a 300 MHz NMR spectrometer. One dimensional proton and carbon spectra were acquired using a broadband observe (BBFO) probe with 20 Hz sample rotation at 0.1834 and 0.9083 Hz/Pt digital resolution respectively. All proton and carbon spectra were acquired with temperature control at 30° C. using standard, previously published pulse sequences and routine processing parameters.
