A rhodium-catalyzed cyanation of chelation assisted C-H bonds is described. This process provided a useful method for the preparation of diverse 2-cyanated arylphosphonate and related compounds in good yields. The reaction tolerates a variety of synthetically important functional groups. A question of chelation: A rhodium-catalyzed cyanation of chelation assisted C-H bonds is described employing NCTS as an efficient cyanating reagent. The present method allowed the synthesis of various 2-cyanated arylphosphonate and related compounds in moderate to good yield. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. Source

A highly efficient and mild [bmIm]OH-catalyzed α-hydroxylation of phosphonates using O2 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 α-hydroxy phosphonates. © 2015 American Chemical Society. Source

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.
