It was found for the first time that organic alkali metal compounds serve as highly efficient precatalysts for the hydrophosphonylation reactions of aldehydes and unactivated ketones with dialkyl phosphite under mild conditions. For ketone substrates, a reversible reaction was observed, and the influence of catalyst loading and reaction temperature on the reaction equilibrium was studied in detail. Overall, the hydrophosphonylation reactions catalyzed by 0.1 mol % n-BuLi were completed within 5 min for a broad range of substrates and generated a series of α-hydroxy phosphonates in high yields.

, p. 1753 - 1760 (2015/02/02)
Magnetic-nanoparticle-supported phosphotungstic acid has been used to efficiently catalyze the hydrophosphonylation reaction of isatins, imines, and aldehydes using dimethyl and diethyl phosphite as a nucleophile to give the corresponding α-hydroxy and α-amino phosphonates in excellent yields for a wide range of substrates. The reaction conditions were simple, green, and efficient. The catalyst was recycled up to five times with retention of its activity. Based on the NMR spectroscopy studies, a probable catalytic cycle was proposed.

, p. 1573 - 1576 (2014/01/06)
An efficient phospho-aldol reaction of aldehydes catalyzed by N-heterocyclic carbenes (NHCs) has been developed. With 10 mol% stable NHC 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene, various aldehydes reacted with dialkylphosphites smoothly to provide α-hydroxy phosphonates in 59% -99% yield. In this process, NHC was assumed to function as a carbon-centered bronsted base. Copyright
