✦ Synopsis

Abstraction of hydrogen chloride from P-chloroalkane phoaphonic esters' and some other reactions 293 result in the formation of l-alkene phosphonic esters with trans arrangement of phosphcnic groups and bulky substituents.

The tie compounds are much less available.495

The purpose of thie paper is to show the catalytic hydrogenation of l,a-diene phosphor& esters to be useful as a general route to cis-l-allcene phosphor&&tea. This hydrogenation carried out in alcohol solution at ordinary pressure and temperature with 49% Pd/CaC03 as a catalyst is highly selective
