Zinc Chloride Doped Natural Phosphate as 1,3-Dipolar Cycloaddition Catalyst

Phosphates: New Generation of Liquid-Phase Heterogeneous Catalysts in Organic Chemistry

“…We found that it promotes the reaction depicted in Scheme 43. Thus, 71% yield was obtained after 48 h, 19 h and 7 h using, ZnCl 2 , NP and ZnCl 2 /NP, respectively [114].…”

Catalysis by phosphates: A simple and efficient procedure for transesterification reaction

“…These new phosphates catalysts have been used to afford various organic transformations. Thus ZnCl 2 /NP has been used as excellent acidic catalyst for Friedel-Crafts alkylation [6], 1,3-dipolar cycloaddition [7], acyclonucleoside synthesis [8] and 3,4-dihydropyrimdin-2(1H)-one synthesis [9]. KF/NP catalyzed efficiently nitrile hydration [10], Michael addition [4,[11][12][13], Knoevenagel condensation [5,14], flavanone synthesis [15], nucleobase alkylation [16] and nucleoside synthesis [17].…”

Ca10(PO4)6(OH)2-modified carbon-paste electrode for the determination of trace lead(II) by square-wave voltammetry

“…During the past 6 years, our group have studied the use of phosphate compounds [15] to promote organic transformation [16] and have shown that its mild basic and acidic properties can be exploited in many synthetic applications [17].…”
