摘要：

The iron-containing ionic liquid butylmethylimidazolium tetrachloroferrate (bmim-FeCl4) proved to be an efficient and recyclable catalyst for the hydroxymethylation of beta-keto esters using aqueous formaldehyde and a low catalyst loading of up to 0.1 mol-% without co-solvents or additional surfactants. An useful and high-yielding approach to hydroxymethylated keto esters as well as to 3-disubstitued butyrolactones via tandem hydroxymethylation-lactonization could thus be established.
