“…Since then, this reaction got the attention of chemists, a numerous of different catalysts were used to obtain the α-hydroxyphosphonates such as guanidine hydrochloride 18 , Amberlyst-15 19 , natural phosphate 20 On the other hand, Oil shale raw matter is considered as an energy source by conversion this matter to energy and chemical products through the thermochemical conversion technology 29 . A number of environmental alternatives have also been developed using Moroccan oil shale as adsorbent material to remove industrial dyes, heavy metals, and radioactive elements [29][30][31][32][33][34][35][36] .…”

A new heterogeneous catalyst has been developed based on moroccan oil shale raw matter. This new support was used in the α-hydroxyphosphonates synthesis by Pudovik pathway using dialkylphosphites and carbonyls compounds. The transformation was performed by using oil shale-based catalyst under room temperature and by ultrasound-assisted synthetic approach. Both approaches have been found to be efficient in this organophosphorus synthesis. The reaction was carried out with a high yield in dry media, the catalyst is separated easily and reused several times without losing its activity.
