应用多核(1H, 13C, 15N和51V)NMR、二维扩散排序谱(2D DOSY)、变温NMR以及电喷雾质谱(ESI-MS)等谱学方法研究草酸双过氧钒配合物与精氨酸(Arg)的相互作用,发现该相互作用体系可生成以氨基配位的新过氧钒物种[OV~(O2)2Arg]-,研究结果表明综合利用上述谱学方法有助于揭示此类相互作用体系的反应过程和配位机制.

Coordination interactions between oxalate-oxodiperoxovanadate {K3[VO(O2)2(C2O4)]·H2O, abbr. bpV(oxa)} and arginine (abbr. Arg) in solution were studied by 1D multinuclear ( 1H, 13C, 15N, and 51V) NMR, 2D diffusion ordered spectroscopy (DOSY), variable temperature NMR, and electrospray ionization mass spectrometry (ESI-MS). Spectroscopic results indicated that a new peroxovanadate species [OV(O2)2Arg]- was formed in which Arg coordinates to vanadium through amino group. It is proved that these methods are useful for analyzing and characterizing the reaction processes and coordination modes in this kind of the interaction systems.

Key words: peroxovanadate, arginine, interaction, NMR, DOSY, ESI-MS
