The μ2-O atom in Anderson polyoxometalates was regioselectively activated by the introduction of protons, which, upon functionalization with triol ligands, could afford a series of unique χ isomers of the organically-derived Anderson cluster {[RCC(CH2O)3]MMo6O18(OH)3}(3-). Herein proton-controlled isomer transformation between the δ and χ isomer was observed by using the fingerprint region in the IR spectra and (13)C NMR spectra.
通过引入质子对安德森多金属氧酸盐中的μ2-O原子进行区域选择性活化，在用三元醇配体进行功能化时，可得到一系列有机衍生的安德森簇{[RCC(CH2O)3]MMo6O18(OH)3}(3-)的独特χ异构体。在此，利用红外光谱和(13)C核磁共振光谱的指纹区域观察到了δ异构体和χ异构体之间的质子控制异构转化。
