Sulfated zirconium oxide-decorated magnetite KCC-1 as a durable and recyclable adsorbent for the efficient removal of asphaltene from crude oil

“…6a). 34,41,44 A slight weight loss below 220 C was also attributed to the removal of adsorbed water (Fig. 6a).…”

A comprehensive review on synthesis of dihydropyrimidione via Biginelli reaction catalyzed by reusable magnetic nanocatalyst (from 2020–till date)

“…Eventually, the catalyst could be readily separated from the reaction medium and utilized for five consecutive runs with no loss of catalytic activity or effectiveness. [ 146 ]…”

“…Benzyl alcohol, ethyl acetoacetate, and urea Fe 3 O 4 @Cu-Mn Aerobic oxidative condition 97 [146] 20.…”

“…Eventually, the catalyst could be readily separated from the reaction medium and utilized for five consecutive runs with no loss of catalytic activity or effectiveness. [146] In 2020, Abadi and his colleagues carried out the Biginelli condensation reaction of 1,3-dicarbonyl compounds, terephthalic aldehyde, and (thio) urea or guanidine along with tri-metallic Fe-Co-V/Zeolite and Fe-Co-Mo/Zeolite composite nanostructures was reacted to produce Bis (dihydropyrimidinone) derivatives (Scheme 20). TEM, field emission scanning electron microscopy (FESEM), XRD, and FT-IR were used to characterize the structural functions and morphological observations of the catalyst.…”

Efficient reduction of nitro compounds and domino preparation of 1-substituted-1H-1,2,3,4-tetrazoles by Pd(ii)-polysalophen coated magnetite NPs as a robust versatile nanocomposite

“…For example, Nasseri et al reported domino protocols for the preparation of benzimidazole derivatives and Biginelli reactions from alcohols using a Cu–Mn bimetallic complex immobilized on magnetic NPs. 18 Hydroformylation/aldol condensation, 19 synthesis of cyclic amidines, 20 one-pot synthesis of vinylsilanes, 21 synthesis of polysubstituted pyrroles and lamellarin R, 22 and synthesis of multisubstituted tetrahydrobenzofuran derivatives 23 are some recent applications of domino reactions in organic synthesis.…”
