Abstract

Abstract A new catalytic system for the alkylation of H-phosphonates and diphenylphosphine oxide with N-tosylhydrazones has been developed. In the presence of copper (I) iodide and base, H-phosphonates react with N-tosylhydrazones to afford the corresponding coupled alkylphosphonates in good to excellent yields without any ligands. Alkylphosphonates can also be prepared in a one-pot process directly from carbonyl compounds without the ...
