for the preparation of N-substituted 2-phopshorylpyrrolidines from readily available 4,4-diethoxybutan-1-amine derivatives and P (III) acid chlorides is described. The presented method benefits from simple reaction and work-up procedures, mild reaction conditions, avoids protecting group introduction-removal stages and provides a straightforward access to target compounds.

Phosphorylacetic acid esters containing the menthoxy fragment at the phosphorus atom or at the carbonyl group were synthesized. The configurations of the enantiomerically pure compounds, viz., methyl (ethoxy)(menthyloxy)phosphorylacetate and menthyl [(2-chloro-ethoxy)(4-dimethylaminophenyl)phosphoryl]acetate, were established by X-ray diffraction and NMR spectroscopy.

selective ethyleneoligomerization. Single crystal analysis suggested that the alkyl substituents in the scaffold of the alkylphosphanyl PNP ligands may effectively induce the complex structure and consequently the catalytic performance. Density functional theory (DFT) calculations revealed that in comparison to the trimerization pathway, the rate-determining states in the tetramerization pathways of
