Palladium-catalyzed C(sp3)–P(III) bond formation reaction with acylphosphines as phosphorus source

Palladium-catalyzed C(sp3)–P(III) bond formation reaction for alkyl substituted phosphines preparation was developed. In this reaction, various alkyl bromides and limited alkyl chlorides reacted with acylphosphine under relative mild and easily accessible condition, and differential phosphines were afforded in good yields. This reaction made up the application of palladium catalysis in C(sp3)–P(III) bond formation, and indicated a practical application of acylphosphine as a phosphination reagent.

Copper-catalyzed synthesis of alkylphosphonates from H-phosphonates and N-tosylhydrazones

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 isolation of tosylhydrazone intermediates.

Acceleration of nucleophilic addition to vinylphosphonates and vinyl phosphine oxides by chlorotrimethylsilane

Chlorotrimethylsilane significantly accelerates the conjugate addition of alkyl cuprates to vinylphosphonates.
