- Solvent-free sonochemical preparation of α-aminophosphonates catalyzed by 1-hexanesulphonic acid sodium salt
-
1-Hexanesulphonic acid sodium salt was found to be an efficient catalyst for the green synthesis of α-aminophosphonates by the coupling of aldehydes/ketone, an amine and triethyl phosphite under ultrasound irradiation at ambient temperature for appropriate time to furnish the desired product in good to excellent yield under solvent-free condition.

- Magnetic ZnO?CuO?Iron ore nanocomposites as a green and highly efficient heterogeneous nanocatalyst for solventless synthesis of α-aminophosphonates
-
A green novel synthesis of ZnO?CuO?Iron ore nanocomposites as a novel and magnetic heterogeneous nanocatalyst is used for the one-pot synthesis of α-aminophosphonates under solventless conditions. This study benefits from the magnetic iron ore acting as a multi-mineral Lewis acid system, the green properties and the large surface area due to its nanostructure. Moreover, scanning electron microscope analysis confirmed that the nanocatalyst gave an excellent yield and good recyclability; which, even after the 10th cycle of the model reaction retained its potential with no significant loss of catalytic activity.

- Radical Cation Salt-initiated Aerobic C?H Phosphorylation of N-Benzylanilines: Synthesis of α-Aminophosphonates
-
A radical cation salt-initiated phosphorylation of N-benzylanilines was realized through an aerobic oxidation of the sp3 C?H bond, providing a series of α-aminophosphonates in high yields. An investigation of the reaction scope revealed that this mild catalyst system is superior in good functional group tolerance and high reaction efficiency. The mechanistic study implied that the cleavage of the sp3 C?H bond was involved in the rate-determining step.

- Reusable zinc oxide nanoflowers for the synthesis of α-aminophosphonates under solvent-free ultrasonication
-
A simple wet chemical method is used to prepare zinc oxide nanoflowers (ZnO NFs) which were subjected to various characterization techniques such as XRD, FTIR, UV–Vis, FE-SEM, and XPS. XRD pattern indicates pure, crystalline, and monodispersed form with hexagonal wurtzite phase. The 3-D flower shape morphology with hexagonal ZnO nanorods was confirmed in FE-SEM. The synthesized ZnO NFs was used to study catalytic behavior in Kabachnik–Fields reaction under controlled ultrasound cavitation technique. High surface-to-volume ratio of ZnO NFs and the effect of ultrasonication enhances the yield of α-aminophosphonate. The catalyst was recycled and reused four times without any significant loss of its catalytic activity. Moreover, existing method becomes attractive and practical due to its easy, clean, fast, cost-effective, and eco-friendly procedure.

- A green one-pot three-component synthesis of α-aminophosphonates under solvent-free conditions and ultrasonic irradiation using Fe3O4@SiO2-imid-PMAn as magnetic catalyst
-
An efficient and environment friendly process for the synthesis of α-aminophosphonates has been devised. Through a one-pot three-component condensation of various aldehydes, amines, and triethyl phosphite in the presence of Fe3O4@SiO2-imid-PMAn nanoparticles as magnetic catalysts under solvent-free conditions and ultrasonic irradiation, α-aminophosphonates were obtained with excellent yields. The reactions under solvent-free conditions at room temperature are compared with the ultrasonic-assisted reactions. This new procedure has notable advantages such as short reaction time, excellent yields, easy purification, and the absence of any tedious workup or purification. The aforementioned catalyst could be easily recovered by an external magnetic field and can be reused for six consecutive reaction cycles without significant loss of activity. In addition, SEM and DLS of the catalyst after the reaction cycle were investigated.

- A Green Approach to the Synthesis of α-Amino Phosphonate in Water Medium: Carbene Insertion into the N-H Bond by Cu(I) Catalyst
-
Synthesis of amino phosphonates is more important owing to their significant applications in the biological systems. There are few methods already known in the literature to make these molecules; however, known methods have their own disadvantages. In this regard, synthesis of different kinds of amino phosphonates have been achieved via phosphonate substituted carbene insertion into the N-H bond of aniline catalyzed by readily available copper salt under mild reaction conditions in water. In order to find an efficient catalyst for carbene insertion reaction in neat water, a large number of transition metal catalysts were screened, and we found that the [Cu(CH3CN)4]ClO4 was the best catalyst under employed reaction conditions. Using this environmentally benign methodology (copper catalyzed reaction in water), a large number of biologically important amino phosphonates have been synthesized, isolated (37 examples), and characterized using standard analytical and spectroscopic techniques.

Abstract: Nickel (II) sulfate hexahydrate is used for the first time as an efficient catalyst for the one-pot synthesis of α-aminophosphonates by three-component condensation reaction of aromatic aldehyde, primary amine, and diethylphosphite under mild and eco-friendly conditions. NiSO4·6H2O was used with a catalytic amount of 5?mol% at room temperature, without solvent in the reaction. A series of the desired α-aminophosphonates are obtained after a simple work-up procedure, with excellent yields (up to 92?%) within a short reaction time of 10–20?min in all cases. This heterogeneous catalyst was reused several times with the same activity. The present approach offers the advantages of a clean reaction, simple methodology, easy purification, and economic availability of the catalyst.

A novel magnetic Br?nsted acid catalyst was synthesized based on growing poly(amidoamine) dendrimers on the surface of magnetic nanoparticles. After the dendronizing process, the MNP coated PAMAM was functionalized by chlorosulfuric acid to form an acid catalyst. Because of dendrimer coating of MNPs, catalyst shows good loading level of acidic groups on the surface. Also zwitterion nature of catalyst surface improves the catalytic activity. This new catalyst is proven to be highly effective in the synthesis of α-aminophosphonate compounds in a green way.
