    • Experimental Details. Melting points were measured on a Büchi 520 apparatus and were uncorrected. 1H NMR, 13C NMR, 14N NMR, and 15N NMR spectra were obtained on a Bruker Avance with 400 MHz proton frequency, 15N NMR were measured in inverse 2D mode (gs-HMBC, 1H NMR spectra in CDCl3 were referenced to tetramethylsilane (TMS) at δ, 0.0 ppm; 13C NMR spectra refer to the solvent signal center at δ, 77.0 ppm. Other solvents as follows: DMSO-d6: 2.50 ppm (1H, 39.70 ppm (13C, CD3)2CO: 2.04 ppm (1H, 29.8 ppm (13C, C6D6: 7.20 ppm (1H, 128.0 ppm 13C, N NMR spectra were externally referenced to nitromethane at δ, 0.0 ppm. IR spectra were obtained on a Bruker 'Vector 22' FT IR as KBr IR. Mass spectra were recorded on a Hewlett Packard system 'M
