  Hydrogenation of α-oxophosphonates with molecular hydrogen catalyzed by palladium on carbon carrier as synthesis procedure for α-hydroxyphosphonates

  摘要：

  Hydrogenation with molecular hydrogen of substituted benzoylphosphonic acids ethyl esters provides a convenient preparation method for diethyl [hydroxy(aryl)methyl]phosphonates. Both the palladium on activated carbon and the palladium immobilized in a chitosan matrix applied on a carbon carrier sibunit can be employed as catalysts.

  Lanthanide anilido complexes stabilized by the 2,6-diisopropylanilido ligand have been synthesized and characterized, and their catalytic activity for hydrophosphonylation reaction was explored. A reaction of anhydrous LnCl3 with 5 equivalents of LiNHPh-iPr2-2,6 in THF generated the heterobimetallic lanthanide–lithium anilido complexes (2,6-iPr2PhNH)5LnLi2(THF)2 [Ln = Sm(1), Nd(2), Y(3)] in good isolated yields. These complexes are well characterized by elemental analysis, IR, NMR (for complex 3) and single-crystal structure determination. Complexes 1–3 are isostructural. In these complexes, the lanthanide metal ion is five-coordinated by five nitrogen atoms from five 2,6-diisopropylanilido ligands to form a distorted trigonal bipyramidal geometry. The lithium ion is coordinated by two nitrogen atoms from two 2,6-diisopropylanilido ligands, and one oxygen atom from a THF molecule. It was found that these simple lanthanide anilido complexes are highly efficient for catalyzing hydrophosphonylation reactions of various aldehydes and unactivated ketones to generate α-hydroxyphosphonates in good to excellent yields (up to 99%) within a short time (5 min for aldehydes, 20 min for ketones). Furthermore, the mechanism of hydrophosphonylation reactions has also been elucidated via1H NMR monitoring of reaction.

  Nanosize magnetic particles coated with magnesium oxide (core/shell nanoparticles) have been prepared and used for the synthesis of 1-hydroxyalkyl phosphonates. Catalytic activity studies show that the magnetic particles coated with magnesium oxide have highly catalytic activity toward the phosphorylation of aldehydes for the synthesis of 1-hydroxyalkyl phosphonates under solvent-free conditions. Reusability of the prepared magnetic nanoparticles was successfully examined five times with a very slight loss of catalytic activity.
