An effective catalytic method for α-phosphoryloxylation of ketones is reported. When ketones were reacted with phosphates in the presence of iodobenzene as the recyclable catalyst and m-chloroperbenzoic acid as the terminal oxidant in acetonitrile at room temperature, the α- phosphoryloxylation of ketones took place easily and the corresponding keto phosphates were obtained in moderate to good yields. © Georg Thieme Verlag Stuttgart.

Ester hydrolysis at oil-water interface by lipase covalently immobilized on ionic liquid-modified magnetic nanoparticles was investigated. Magnetic supports with a diameter of 10-15 nm were synthesized by covalent binding of ionic liquids (chain length C 4 and C 8 and anions Cl -, BF 4 -, and PF 6 -) on the surface of Fe 3O 4 nanoparticles. Lipase was covalently immobilized on Fe 3O 4 nanoparticles using ionic liquids as the coupling reagent. Ionic liquid-modified magnetic nanoparticle-grafted lipase preferentially located at the oil-water interface. It has higher catalytic activity than its native counterpart. A modified Michaelis-Menten model was used to elucidate the effect of stirring rate, aqueous-organic phase ratio, total amount of enzyme, and ester chain length. The influences of these conditions on esters hydrolysis at oil-water interface were consistent with the introduction of the ionic liquids interlayer. Ionic liquids could be used to control the oil-water interfacial characteristics during lipase catalyzed hydrolysis, and thus control the behavior of immobilized lipase. © 2011 American Institute of Chemical Engineers (AIChE).
