二甲亞?對 之親合力可從 (方程式無法摘錄) 反應在不同酸性溶液之正逆
反應動力學測定之結果獲得，當溫度為25°C，而 ＝0.01、0.05及0.1 M時，反應平衡常數分別為7.9× ，3.4×
及1.3× 親合力隨溶液酸度的增加而減低，主要乃因形成反應速率變慢之故，水離反應速率並未因錯合物之
質子化而顯著改變，嘧啶及N- 甲基??錯合物之親合力亦經探討，其隨酸度之變化情形與二甲?錯合物相似，當
氧化成Fe(III)時，錯合物並未有S→O之結合異構現象發生，而錯合物經由水離反應分解。當pH＝5
及2時，其 分別為2.5 × 及4.8 × 。 - 英文摘要：
The affinities of dimethylsulfoxide on were obtained by the kinetic results of the for-
wars anu reverse rate measurements of the reaction (方程式無法摘錄)
in aqueous solutions of various acid concentrations. The equilibrium quotients at 25?C are 7.9× ,
3.4× and 1.3 × at = 0.01, 0.05 and 0.1 M, respectively. The decrease in affinity with respect
to acidity is mainly due to the diminution in the specific rate of formation. The rate of aquation of the
complex is not significantly affected by the protonation of the complex. A similar
trend is also observed for the affinities of the pyrimidine and the N-methylpyrazinium complexes. There is
no S→O linkage isomerization observed when is oxidized to Fe (III), and the complex
disappears through aquation with being 2.5× and 4.8×10 at pH = 5 and pH = 2, re-
spectivety.
