PS-BEMP was used as a heterogeneous catalyst for the phospha-Michael addition of phosphorus nucleophiles to a variety of electron-poor alkenes. The addition reactions were generally performed with equimolar amounts of reagents under solvent free conditions. The protocol proved to be very efficient for the addition to aromatic, non-aromatic and cyclic ketones, giving good yields (78-85%) in all cases. The protocol was also extended with good results to α,β-unsaturated esters and nitriles. This demonstrates that PS-BEMP is a good catalyst for the phospha-Michael addition to electron-poor alkenes.

Reaction of dialkyl phosphites with benzalacetophenone (chalcone) and benzalacetone in the presence of cyclohexylamine as a catalyst is a convenient preparative method for selective phosphorylation of conjugated α, β-unsaturated carbonyl compounds at the carbonyl group. The kinetics of cyclohexylamine-catalyzed addition of dialkyl phosphites to cis- and trans-chalcones is studied, and factors are revealed that influence the reactivity of addends in this reaction.
