beta-Ketophosphonates were prepared via AgNO3-catalyzed hydration of alkynylphosphonates with a dramatic rate-enhancement effect of methanol. This benign aqueous-methanol method catalyzed by a low-(c)ost catalyst has simple, atom-economical procedure, and was used effectively with a wide range of substrates. (C) 2014 Elsevier Ltd.
