infrared and proton magnetic resonance spectra. This compound was regarded as a thallous phenolate derivative; however, the effect of chelation by the 2,4-pentanedionate moiety due to a longrange anionotropy was observed. The acetyl proton exchange of the Tl(I) compound in D2O was observed by a PMR investigation. It was found that the methyl-proton exchange was inhibited by chelation.

2,4-戊二酮的
铊化合物,并通过红外和质子磁共振光谱确定了其结构。该化合物被认为是一种
铊酚盐衍
生物;然而,由于长程阴离子性,2,4-
戊二酸部分的螯合效应被观察到。通过 PMR 研究观察到 Tl(I) 化合物在 D2O 中的乙酰质子交换。发现甲基-质子交换被螯合抑制。
