Reaction of Chloroacetylenephosphonate with Acetoacetic Ester and Its Analogs

摘要

Recently we have shown that chloroacetylenephos-phonates react with several CH-acids (1,3-diketones) with the participation of K2CO3 to form potassium derivatives of 1,3-dicarbonyl compounds containing at the carbon atom of the methylene group a dialkoxy-phosphorylacetylenyl substituent [1].
