“…As a continuation of the previous works developed by our researchers [27][28][29][30][31][32][33][34][35][36][37][38][39] , which consist on the valorization of Moroccan phosphates in the field of organic synthesis, and the development of green and sustainable chemistry, this paper reports the first and an easy preparation method for TiP2O7 from the modifications of phosphate fertilizers MAP, DAP and TSP by titanium tetrachloride (TiCl4). The characterization of TiP2O7 was realized using spectroscopic and microscopic technics such as XRD, IR, SEM, and EDX.…”

A simple and efficient method for the synthesis of quinazolin-4(3H)-one derivatives via condensation of anthranilamide with aromatic aldehyde catalyzed by monoammonium phosphate (MAP), diammonium phosphate (DAP), and triple superphosphate (TSP), were developed. The modification of these three phosphate fertilizers using titanium tetrachloride (TiCl4) has increased their catalytic efficiency. The prepared titanium phosphate (TiP2O7) was characterized using microscopic and spectroscopic methods, namely X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX), and infrared spectroscopy (IR). The TiP2O7 was applied for the first time as a heterogeneous catalyst in quinazolin-4(3H)-ones synthesis. High yields and short reaction times were observed in the determined optimal condition (solvent nature, volume, and catalyst amount). This study shows that the TiP2O7 presents an exciting catalytic activity and long-term durability compared to those of MAP, DAP, and TSP.

“…As a continuation of the previous studies published by our researcher's team on the design and application of phosphate catalysts in organic reactions . In order to valorize the Moroccan phosphate, one proposes a process for the preparation of Co 3 (PO 4 ) 2 , by a simple and less expensive method compared to that reported previously, that consists to modify the fertilizer phosphates mono‐ammonium phosphate MAP by Co(NO 3 ) 2 .…”

This work presents a simple process for the preparation of Cobalt Orthophosphate (Co 3 (PO 4 ) 2 ), by modifying phosphate fertilizer mono-ammonium phosphate (MAP) by cobalt nitrate (Co(NO 3 ) 2 ). Co 3 (PO 4 ) 2 has been characterised using microscopic and spectroscopic methods namely X-ray diffraction (XRD), infrared spectroscopy (IR) and scanning electron microscopy (SEM). It is the first time that Co 3 (PO 4 ) 2 is used as a heterogeneous catalyst in the condensation between an aryl aldehyde, 4-hydroxycoumarin and malononitrile. The results show that Co 3 (PO 4 ) 2 is an effective catalyst for one-pot synthesis of 3,4-dihydropyrano [3, 2-c] chromene. The optimisation of each reaction parameter allows achieving excellent results in terms of time and yield. The application of Co 3 (PO 4 ) 2 as catalyst in the 3, 4-dihydropyrano [3, 2-c] chromene derivatives synthesis offers certain advantages such as shorter reaction time, simple treatment, furthermore, the catalyst possesses a great capacity for reutilization and therefore its application contributes to the development of green chemistry.[a] A.

“…The most of these catalysts present some inconvenient since they are toxic, expensive and non-recyclable. Taking in consideration all these factors, the aim of this study is to propose a new, simple, and effective method for the synthesis of 1-(benzothiazolylamino) methyl-2-naphthol derivatives using phosphate fertilizers monoammonium phosphates (MAP), diammonium phosphate (DAP) and triple superphosphate (TSP) [17] as natural and cheap catalysts, which are well known for their valuable catalytic activities and high recycling and reuse capacity [18][19].…”

The present work focused on developing a new protocol of the 1-(benzothiazolylamino) methyl-2-naphthol derivatives synthesis by condensation of three compounds, i.e. aromatic 2-naphthol, 2-aminobenzothiazole and aldehyde. Furthermore, this reaction was carried out in the presence of three heterogeneous phosphate catalysts: monoammonium phosphates (MAP), diammonium phosphate (DAP), and trisuperphosphate (TSP). Moreover, this method offered many advantages, such as: very high yields, shorter reaction times, and the catalysts, can be easily recovered and reused without any loss of their catalytic activities.
