Carbamoylmethylphosphine oxide functionalised porous crosslinked polymers towards sequential separation of uranium (VI) and thorium (IV)

A new class of highly crosslinked porous polymeric materials with an ethylene glycol dimethacrylate (EGDMA) backbone appended with carbamoylmethylphosphineoxide (CMPO) ligands has been synthesized via precipitation polymerization. The polymers were charac

Diphenylmorpholine CMPO: Synthesis, coordination behavior and extraction studies of actinides

Carbamoylmethyl phosphine oxide (CMPO) derivatives are well known ligands in the separation and extraction of trivalent lanthanides and actinides from nuclear waste. The substituents of CMPO play major role in their selectivity and extractability. We report the synthesis and characterization of diphenylmorpholine carbamoylmethyl phosphine oxide (DPMCMPO) (L1) and diphenyl-N,N-diethyl carbamoylmethyl phosphine oxide (DPDECMPO) (L2) using various spectroscopic techniques, such as FT-IR, 1H, 13C, and 31P NMR. The molecular structure of DPMCMPO is confirmed by single crystal XRD analysis. The present study aims to understand the influence of substituents on ‘N’ atom of L1 (morpholine based DPMCMPO) and L2 (diethyl substituted DPDECMPO) ligands for the extraction of some selected actinide ions such as Th(IV), U(VI) and Am(III). The geometry and electronic structure of these ligands and their respective complexes with Th(NO3)4 and UO2(NO3)2 are further explored using density functional theory (DFT) calculations. The employed ligands (L1 and L2) show greater distribution values for Th(IV) over U(VI), due to strong “ligand-Th” complexation ability as suggested by DFT calculations.

Reaction of (2-methoxyprop-2-yl)diphenylphosphine oxide with alkyl bromides

Treatment of (2-methoxyprop-2-yl)diphenylphosphine oxide with alkyl bromides affords alkyl(diphenyl)phosphine oxides in good yields.

Complex formation of some carbamoylmethylphosphine oxides and methylenediphosphine dioxides with alkali metal cations. The "anomalous aryl enhancement" effect

Conductometry in anhydrous hexane at 25°C was used to measure the stability constants of alkali cation complexes of a series of N,N-diethylcarbamoylmethylphosphine oxides and methylenediphosphine dioxides. The "anomalous aryl enhancement" effect is the strongest in the complexes with tetraphenyldiphosphine dioxide.

ALKYLATION REACTIONS OF DIALKYL HYDROGEN PHOSPHITES AND DIARYLPHOSPHINE OXIDES UNDER PHASE-TRANSFER CONDITIONS

It was shown that phosphonates and tertiary phosphine oxides can be synthesized by the alkylation of acid phosphites and diarylphosphine oxides in a nonpolar solvent in presence of solid potassium hydroxide and potassium carbonate and also catalytic amounts of 18-crown ether (or in its absence). (Diarylphosphinyl)methyl ethers of mono- and oligo-etylene glycols were synthesized by the reactions of diaryl(chloromethyl)phosphine oxides with lithium glycolates
