“…These protocols use either Brønsted acids (6) metal catalysts such as sulfonic acid nanomagnetic (7) and the iron (III) tosylate (8), bis[(L)-prolinato-N,O]Zn-water ( 9), the 1glycyl-3-methyl copper chloride imidazolium (II) (10), but the use of transition metals is toxic and dangerous. The aim of this work is to use a simple synthetic, green, and effective protocol for the synthesis of dihydropyrimidin-2(1H)-one and dihydropyrimidin-2(1H)-thione derivatives using three phosphate compounds as catalysts, in addition to traditional reagents of Biginelli reaction: urea or thiourea, ester β-ketones and aldehyde in ethanol.…”

A simple, efficient, and green procedure has been developed for the synthesis of dihydropyrimidinones (Products of Biginelli) using phosphate fertilizers (mono-ammonium phosphate (MAP), di-ammonium phosphate (DAP) and triple super phosphate (TSP)) as catalyst. The one-step reaction involved the three compounds, which are registered aromatic aldehydes, dicarbonyl compounds and the urea/thiourea. This new method provides some advantages such as obtaining excellent yields (98%), as well as the short duration of the reaction, which may attain 2 minutes. These catalytic heterogeneous systems present also the advantage of being easily recycled.

“…Thirdly, some of them are not miscible with organic solvents and hence they afford an alternative for nonaqueous nature for two-phase systems. Finally, ionic liquids have good thermal/chemical stability and nonflammability, and can be reused to offer similar performance in chemical transformations [1,[12][13][14][15][16][17] As a result, the extraction of sulfur using ILs to remove sulfur compounds such as thiophene has been extensively described.…”

Acidic carboxyl functionalized poly(ionic liquid) (CFPIL) has been synthesized and characterized by various techniques like FT-NMR,Fourier transform infrared spectroscopy (FTIR). In this work, deep oxidative desulfurization of model oil (thiophene dissolved in iso-octane) byCFPIL catalyst was carried out in presence of 30 wt% H2O2 solution as an oxidant. The effects of the hydrogen peroxide, amount of CFPIL,temperature-time and recyclability are scrutinized systematically. It was found that the effective molar proportion of H2O2 to sulfur was 4:1 at 70 °Cin 180 min with 0.6 g catalyst, removing 100% thiophene from model oil. This method has shown high efficiency for the removal of thiophene,which is difficult to remove from the oil than benzothiophene and dibenzothiophene. Additionally, an oxidative desulfurization mechanism hasbeen proposed according to the experimental results. This catalytic system by CFPIL offers advantages such as higher efficiency, low amount ofionic liquid, simple work up for separating oil from the catalyst and ease of recycling. This protocol inclines to show that diesel fuels in industrycan be purified to sulfur-free or ultra-low sulfur fuels by further deep oxidative desulfurization with CFPILs after hydrodesulfurization.
