New o-substituted diphenylphosphinic amide ligands: synthesis, characterization and complexation with Zn²⁺, Cu²⁺ and Y³⁺

Abstract

Phosphinic amide derivatives have drawn significant attention in coordination chemistry and have been incorporated into the design and synthesis of new ligands.

“…In addition, the method was not effective when diphenylphosphine oxide (dPPO) was reacted with butylamine (13% isolated yield) due to oxidative conversion to phosphonic acid (PP-A). Using this aerobic copper-catalyzed dehydrocoupling method, Zhou et al synthesized a phosphoryl amino compound (16) (Figure 7). (butylamine, dibutylamine, hexylamine, cylohexylamine, and methyl alaninate; Table 1, route f) [108].…”

“…Therefore, synthetic P-N compounds are not only researched out of academic interest, but they also have commercial applications. Uses for P-Ns can be separated into 5 main classes: agriculture, industry, analytical chemistry, synthetic chemistry, and medicinal chemistry ( Figure 3) [12][13][14][15][16][17][18]. Due to the inherent physiochemical properties of the phosphorus atom including its polarizability, multivalency, varying oxidation states, and low coordination number, a diverse range of compounds containing the P-N motifs have been synthesized [11].…”
