近年来,多金属氧酸盐(POMs)的有机功能化受到了越来越多的关注,寻找一种简单有效的方法制备有机衍生物具有重要意义。本文中,通过使用DMAP作为活化剂和三乙胺作为HCl清除剂,进行了聚氧乙烯酸酯(Bu 4 N)2[V6 O 13 {(OCH 2)3CCH 2SO 3C 7 H4}2]·2.5CH3CN(化合物1)的甲苯磺酰基酯衍生物的首次报道的合成。通过分别使用叠氮化钠或溴化钠作为亲核试剂,将甲苯磺酰酯转化为叠氮基或卤化物基团。合成了两种多酸盐衍生物(Bu 4 N)2[V6 O 13 {(OCH 2)3CCH 2N 3}2]·4CH 3CN(化合物2)和(Bu 4 N)2[V6 O 13 {(OCH 2)3CCH 2Br}2](化合物3)。通过单晶X射线衍射、元素分析、红外光谱、核磁共振谱、电喷雾质谱、紫外-可见光谱和热重分析对所有化合物的结构和组成进行了表征。本工作为聚氧乙烯酸酯有机衍生物的官能团转化提供了一条新的途径。
Recently, the organic functionalization of polyoxometalates (POMs) has drawn increasing interest, and an easy and effective route to achieve organic derivatives is of great importance. Herein, the first reported synthesis of a tosyl ester derivative of the polyoxometalate (Bu4N)2[V6O13{(OCH2)3CCH2SO3C7H4}2]·2.5CH3CN (compound1) was performed by using DMAP as an activating reagent and triethylamine as an HCl scavenger. The tosyl ester was transformed into an azide or halide group by using sodium azide or sodium bromide, respectively, as the nucleophilic agent. Two derivatives of POMs, (Bu4N)2[V6O13{(OCH2)3CCH2N3}2]·4CH3CN (compound2) and (Bu4N)2[V6O13{(OCH2)3CCH2Br}2] (compound3), were easily obtained. All the compounds were structurally and compositionally characterized by single-crystal X-ray diffraction, elemental analysis, IR spectroscopy, NMR spectroscopy, ESI-MS, UV-Vis spectroscopy and TGA. This work provides a new route for the functional group transformation of organic derivatives of polyoxometalates.
