A sequential one-pot reaction to produce organophosphorus compounds via Knoevenagel condensation and phospha-Michael addition has been realised by utilising ZIF-8 as a heterogeneous catalyst. The combination of 2-methylimidazolate anions and Zn2+ cations in ZIF-8 is revealed to be effective for the efficient promotion of the one-pot reaction.

An efficient, one-pot, di-n-butylamine-catalyzed, three-component synthesis of β-phosphonomalonates has been developed. A wide range of substrates, including aromatic and fused aromatic aldehydes, were condensed with enolizable C-H activated compounds and dialkylphosphites to give the desired products in excellent yields. This method provides an eco-friendly alternative approach to rapid construction of a diversity-oriented library of β-phosphonomalonates.

Ionic tagged propyl amine immobilized on magnetic nanoparticles (MNPs) was synthesized and fully characterized. The novel catalyst (MNPs@PA-IL) was applied in phospha-Michael addition and gave the desired β-phosphonomalonates in good yields. The MNPs supported catalyst with ionic tag could be readily recovered from the reaction mixture using an external magnet. Compared with ionic-free counterpart (MNPs@PA), MNPs@PA-IL present better catalytic activity. The proposed mechanism regarding the MNPs@PA-IL catalyzed phospha-Michael reaction was also discussed.
