A practical route is described for the preparation of 1-phosphono-3(4-di)- substituted-1,3-butadienes based on the Horner-Wadsworth-Emmons (HWE) reaction. Their reactivity in the Diels-Alder (DA) reaction with three selected dienophiles is studied and compared to diethyl 1-phosphono-1,3-butadiene. A particular attention is given to the P-deprotection of cycloadducts from dibenzyl phosphonodienes. New phosphonated bicycles and tricycles have been obtained using this HWE/DA reaction sequence.

Isomerization of diethyl 1-alkynylphosphonates, 1, with Pd[(PPh) 3]4 in refluxing 1,4-dioxane provides 1,3- dienylphosphonates, 2, in satisfactory to excellent isolated yield (45-83%). The reaction is tolerant of chlorides and cyclic

Hydroindation of arylalkynylphosphonates gives a intermediate which can be hydrolyzed to (E)-2-arylvinylphosphonates in InCl3-NaBH 4-MeCN system, the stereoselectivity and yield are rather high, but under the same conditions 2-alkylalkynylphosphonates do not react very well.
Reactions of Copper(I) Halide Complexes of Trivalent Phosphorus with Vinylic Halides
Axelrad, George,Laosooksathit, Surin,Engel, Robert
, p. 5200 - 5204 (2007/10/02)
The direct formation of the vinylic carbon to phosphorus bond has been accomplished via reaction of vinylic halides with copper(I) halide complexes of trialkyl phosphites.In addition, formation of varying amounts of vinylic chlorides may be observed if the reaction is performed by using vinylic bromides with copper(I) chloride complexes of trialkyl phosphites.This halogen-exchange reaction may be made synthetically useful through the employment of copper(I) chloride complexes of triaryl phosphites or phosphines.
