allenylphosphonates and related compounds based on a palladium(0)‐catalyzedreaction of propargylic derivatives with H‐phosphonate, H‐phosphonothioate, H‐phosphonoselenoate, and H‐phosphinate esters. The reaction is stereoselective and stereospecific, and provides a convenient entry to a vast array of allenylphosphonates and their analogues with diverse substitution patterns in the allenic moiety and at the phosphorus
Palladium-Catalyzed Propargylic Substitution with Phosphorus Nucleophiles: Efficient, Stereoselective Synthesis of Allenylphosphonates and Related Compounds
A new, efficient method is developed, based on a palladium(0)-catalyzedreaction of propargylic derivatives with various phosphorus nucleophiles, to produce allenylphosphonates and their analogues with defined stereochemistry in the allenic and the phosphonate moiety.

Allenic phosphonates, readily accessible from 1-alkin-3-ols, the addition products of 1-alkines to aldehydes or ketones, can be transformed to β-ketophosphonates by nucleophilic addition of diethylamine and subsequent hydrolysis of the formed enamines.

The two-coordinate phosphines, (Me3Si)2NP=ESiMe3 (E = N, CH) react smoothly with 1,1-dimethylallene, or with allenic phosphonates, via an ene process to afford novel 2-phospha- or 1,2-diphosphabutadienes.
