Dynamics in N2Uptake by New Ruthenium(II) Tertiary Polyamine Complexes in Aqueous Solution
摘要:
When Ti(III)Cl3 was injected to aqueous 1 mM HCl solutions of trans-[Ru(III)Cl2L1]+ (L1 = 2,5,9,12-tetramethyl-2,5,9,12-tetraazatridecane) under N2, almost quantitative N2 uptake by the reduced ruthenium(II) complex was observed. The first order initial rate constant 2.6 ± 0.3 × 10−4 s−1 was obtained which is the highest value among those so far reported. Much lower rate constants and absorption ratios were observed for homologous ruthenium tertiary polyamine complexes.
