| چکیده | ||
| The high surface area hybrid 1,4-diazoniabicycle[2.2.2] octane chloride xerogel, RH@DABCO, was prepared and used as an environmentally friendly catalyst in the synthesis of phosphoryloxy phosphonate compounds. The present methodology offers several advantages such as mild reaction condition, short reaction time, excellent product yield, simple procedure, recycle exploitation and use of a green and reusable catalyst. Moreover, the 1H and 13C chemical shift values of phosphate-phosphonates were computed and the scaled values were compared with those of experimental NMR spectra. The calculated 1H and 13C chemical shifts were in good accordance with the experimental data. | ||
