β-Hydroxyalkylphosphonates were treated with a weak base such as potassium carbonate in N,N-dimethylformamide to give the corresponding olefins in good yields.
Phosphorohydrazidates have been shown to work as radical precursors by iron-catalyzed aerobic oxidation to generate corresponding phosphonyl radicals. Generated radicals cause intermolecular addition to various alkenes in the presence of molecular oxygen to give beta-hydroxyphosphonate compounds in good yield. (C) 2011 Elsevier Ltd.
