5-Phenyl-1,2,4-thiadiazole-4-15N and 3-methyl-5-phenyl-1,2,4-thiadiazole-4-15N were synthesized from commercially available benazmide-15N. The mass spectra and the 1H, 13C, and 15N-nmr spectra of these compounds, which show various long-range heteronuclear coupling with the 15N-nucleus, are discussed.
5-苯基-1,2,4-噻二唑-4- 15 N和3-甲基-5-苯基- 1,2,4-噻二唑-4- 15 ñ从市售benazmide-合成15 N的质谱并讨论了这些化合物的1 H,13 C和15 N-nmr光谱,这些光谱显示了与15 N核的各种长程异核偶联。
