For a number of compounds, NMR spectra were recorded using a Bruker Avance 500 spectrometer equipped with ***a reverse triple-resonance (1H, 13C, 15N TXI) probe head*** with z gradients and operating at 500 MHz for the proton and 125 MHz for carbon; a Bruker DPX 400 spectrometer equipped with a 5mm reverse triple-resonance (1H, 13C, 19F BBI) probe head operating at 400 MHz for the proton and 100 MHz for carbon; or a Bruker DPX 300 spectrometer equipped with a 5mm dual probe (1H, 13C, QNP) probe head with z gradients and operating at 300 MHz for the proton and 75 MHz for carbon.
