Abstract

Abstract: 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.

Key words: Tsopropyl (dialkoxy phosphoroyl) acetate, Coordination, Constant, NMR
