“…In continuation of our previous research on the synthesis of compounds containing phosphonate moiety, [20][21][22][23][24] we report the synthesis of a-aminophosphonate derivatives (3a-3g) by tree component reaction via Kabachnik-Field reaction catalyzed by eggshell as an efficacious recrystalizable and biodegradable heterogeneous catalyst. The reaction progressed in short time with high yields (Scheme 1).…”

An efficient and eco-friendly green methodology is developed for the synthesis of series of a-aminophosphonate derivatives from diverse aldehydes, anilines and triethyl phosphite by using environmentally benign and cost-effective Eggshells as solid heterogeneous base catalyst. The reaction is conducted by the stepwise one pot condensation through Kabachnick-Fields addition reaction in ethanol at room temperature during 25-30 min. High yield, short reaction time, solvent-free condition, waste to wealth, and optimization with the design of experiment are the major advantages of this method. In addition, this study examines the influence of different solvents, temperature and the amount of catalyst on the yield of the reaction. A single crystal of (2S)diethyl (phenyl) ((4-fluorophenyl)-aminophosphonate (3g) has been obtained after recrystallization from ethanol/dichloromethane (9/1) and selected for X-ray diffraction study. Compound 3g crystallizes in the monoclinic space group P2 1 /c. The structure of the obtained compounds was confirmed by 1 H, 13 C, and 31 P NMR spectroscopy, IR spectroscopy, as well as elemental analysis.

Organophosphorus chemistry is an exciting field of research. Phosphorus-functionalized organic molecules find practical and useful applications in such diverse areas as medicinal, pharmaceutical, agrochemical, and materials chemistries, both on laboratory and industrial scales. Green-chemistry principles are motivating the design and development of newer synthetic methodologies for such beneficial organophosphorus compounds and their analogues. Solvent-free conditions are associated with several practical benefits, including operational simplicity, cost-effectiveness, minimization of waste generation, and reduced pollution, all of which are very much crucial for industrial process development. This review summarizes solvent-free synthetic methodologies for functionalized organophosphorus compounds reported during the period 2016 through 2021.
