Synthesis of Organoimido Derivative (n-Bu_4N)_2[Mo_6O_(18)≡NAr](Ar=o-C_6H_4OH)

采用N,N'-二环己基碳酰亚胺(DCC)脱水法,以摩尔比为n((n-Bu4N)2[Mo6O19])∶n(DCC)∶n(2-氨基酚盐酸盐)=1∶2∶1.34,在无水乙腈中加热至110℃回流14h,通过丙酮/乙醇溶液重结晶数次,得到红褐色针尖状晶体,探讨了最佳反应条件:DCC为2～2.3mmol,反应时间14h,通过元素分析,UV/Vis光谱,IR和1HNMR谱的研究表明,该物质是一种新的六钼酸盐的有机亚胺衍生物(n-Bu4N)2[Mo6O18≡NAr](Ar=o-C6H4OH).利用其与丙烯酸发生酯化反应,通过进一步修饰表明可生成性能优异的有机-无机杂化材料.图3,参9.

（n-Bu,N）2 [Mo6O18≡NAr] （Ar=-o-C6H4OH） was synthesized from a reaction of hexamolybdate （2.16 g, 1 mmol）, DCC （0.41 g,2 mmol）and o-aminophenol（ 0.15 g, 1.34 mmol） in anhydrous acetonitrile at 110 ℃ for 14 h,where DCC is a dehydrating agent. The henna needlepoint compounds were reerystallized in the mixed solution of acetone and ethanol with the volume ratio of 2：1. After studying its UV/Vis,IR,1H NMR spectroscopy and element analysis, the compound is confirmed to be a new monofunctionalized arylimido derivative of hexamolybdate. The organic-inorganic hybrids of high-performance were synthesized by DCC dehydration method with acrylic acid.
