β-Ketophosphonates are an important class of carbonyl compounds which exhibit a wide range of biological activities and outstanding metal-complexing abilities. They are building blocks in organic synthesis, especially as intermediates for the synthesis of α,β-unsaturated carbonyl compounds, chiral β-hydroxy and β-hydroxy phosphonic acids. In this paper, a cheap, simple, convenient and environmentally benign method to synthesize the β-ketophosphonates from alkynylphosphonates was developed, which can be easily prepared in one step from commercial terminal alkynes. In the presence of 10 mol% AgOAc and 4 equiv. of water in methanol at 110 ℃, a broad range of alkynylphosphonates were converted into the corresponding β-ketophosphonates in nearly equivalent conversion through silver/methanol-catalyzed hydration reaction. The presented methodology will provide new strategies for β-ketophosphonates-type natural product and drug synthesis, which has important academic significance and application value.

Key words: alkynylphosphonates, β-ketophosphonate, silver catalysis, hydration reaction
