In order to examine the possibility of Lewis acid–Lewis base (LA–LB) interactions between the boron atom of B(C6F5)2OH and the oxo groups (“yl” oxygen atoms) of uranyl β-diketonato complexes, we have measured the 1H, 11B, 17O, 19F NMR and IR spectra of toluene solutions containing β-diketonato complexes [UO2(acac)2DMSO or UO2(dfh)2DMSO, where acac = 2,4-pentanedionate, dfh = 1,1,1,2,2,6,6,7,7,7-decafluoroheptane-3
为了研究在B(C 6 F 5)2 OH的硼原子与铀酰β-二酮基络合物的氧代基团(“ yl”氧原子)之间路易斯酸-路易斯碱(LA-LB)相互作用的可能性,我们已经测量了包含β-二酮酮络合物[UO 2(acac)2 DMSO或UO 2(dfh)2 DMSO,其中acac = 2,4的甲苯溶液)的甲苯溶液的1 H,11 B,17 O,19 F NMR和IR光谱。-戊二酮酸酯,dfh = 1,1,1,2,2,6,6,7,7,7-十氟庚烷-3,5-二酸酯,DMSO =二甲基亚砜]和B(C 6 F 5)2 OH。含有[B(C 6 F 5)2 OH] / []的UO 2(dfh)2 DMSO和B(C 6 F 5)2 OH溶液的11 B和17 O NMR光谱未显示其化学位移的变化。UO 2(dfh)2 DMSO]比。这表明在B(C 6 F 5)2 OH和UO 2(dfh)2 DMSO之间没有明显的相互作用。另一方面,在含有UO
