Koh,Oh
, p. 2587 - 2590 (1995)
Reaction of 1-phenyl-2-oxo phosphonates with dialkyl phosphite sodium salt gave (E) vinyl phosphonates in good yield.
Stereoselective synthesis of (E) or (Z) α-alkenylphosphonates via α-stannylated phosphonates
Mimouni,About-Jaudet,Collignon,Savignac
, p. 2341 - 2348 (2007/10/02)
α-lithiostannylalkylphosphonates react with aldehydes with the complete elimination of the organotin moiety. The stereoselective formation of the (E) or (Z) α-alkenylphosphonates is closely dependent on the tin substituent.
A One Step Generation of α-Lithiotrimethylsilylalkanephosphonates. A New Preparative Route to Dialkyl 1-(Trimethylsilyl)alkanephosphonates and Vinylphosphonates
Aboujaoude, Elie Elia,Lietje, Stephane,Collignon, Noel,Teulade, Marie Paule,Savignac, Philippe
, p. 934 - 937 (2007/10/02)
Chlorotrimethylsilane phosphonoalkylation in the presence of lithium diisopropylamide (LDA) in excess leads to the generation of an α-silyl α-phosphonyl carbanion which can be protonated, alkylated or converted into vinylphosphonates.
ALKYLIDENEDIPHOSPHONATES ET VINYLPHOSPHONATES: UNE DEMARCHE SYNTHETIQUE SELECTIVE PAR VOIE CARBANIONIQUE

, p. 283 - 300 (2007/10/02)
Phosphonoalkylation of acylchloro-phosphates or -phosphinates in the presence of excess lithium diisopropylamide leads to direct generation of lithiated methylenediphosphonate anions.This stable type of anion can be either protonated in acidic medium to provide tetrasubstituted methylenediphosphonate or alkylated.When aliphatic or aromatic aldehydes are added spontaneous formation of vinylphosphonates is observed.This process is a simple and convenient route to diphosphonic as well as to vinylphosphonic compounds.
