摘要
本文研究La(NO_3)_3与二异丙氧基膦酰乙酸异丙酯(1)和二丁氧基膦酰乙酸异丙酯(H)的配合机理。研究表明在配合物I中La^(3+)离子配位在胱酰基(P=O)和羰基′(C=O)上。并测得的其配合常数K为0.4,而配合物Ⅱ配位在P=O上,其配合常数K为0.04。
The mechanism of coordination of isopropyl (diisopropoxy phosphoroyl) acetate (Ⅰ ) and isopropyi (dibutoxy phosphoroyl) acetate (Ⅱ ) with lanthanum nitrate has been investigated. Results show that the La3+ ion coordinates at P=O and C = O for the coordination compound Ⅰ and at P = O for the Ⅱ. Their coordination constants K were determined in CDCl3 solvent, they are K = 0. 4 for Ⅰ and K=0. 04 for Ⅱ.
