It is provided a method for preparing conjugated diene phosphonate compounds with high reactivity, which can be used to prepare a variety of phosphonate-bearing conjugated dienes. Some of those dienes will become reactive monomers to make polymers and co-polymers. The said method comprises the step of reacting α, β- or β, γ- unsaturated ketones or aldehydes with phosphorous acid or its derivates optionally in a mixture of acetic anhydride and/or acetic acid, to obtain a conjugated diene phosphonate compound having the formula (III)
Cleavage of a carbon-phosphorusbond is achieved under palladium catalysis in an oxidative Heck-type reaction which exploits arylphosphonic acids. The reaction of arylphosphonic acids with alkenes provides arylation products in good yields in the presence of TBAF with trimethylamine oxide as an oxidant.
