  A new, environmentally benign, convenient, and easy method of synthesizing tertiary -hydroxyphosphonates by the triethylamine-catalyzed hydrophosphonylation of unactivated ketones was developed. In the presence of triethylamine, aromatic or heteroaromatic ketones can react with phosphite to form tertiary -hydroxyphosphonates under solvent-free and mild conditions. The proposed method was also suitable for functionalized ketones.

  日期：2015.2.20

  A highly efficient and mild [bmIm]OH-catalyzed a-hydroxylation of phosphonates using O-2 as the oxygen source is described. The employment of ionic liquid under mild reaction conditions makes this transformation green and practical. Especially, this reaction provided a novel and convenient methodology for the construction of quaternary a-hydroxy phosphonates.

  日期：——

  A highly efficient Cu-catalyzed direct hydroxylation of phosphonate compounds has been developed. This transformation provides a powerful method for the synthesis of quaternary α-hydroxy phosphonates in good yields. The direct transformation process, regiospecific selectivity, and good tolerance to a variety of substituents make it an alternative approach to the reported protocols.
