“…It has been reported that IPA can be transformed into aromatics (e.g., mesitylene) during these condensation reactions . However, clear peaks associated with the formation of aromatics were not observed in the blank experiment.…”

“…Based on mass balance considerations (Table ), the blank reaction (Table ), and literature precedents, it is highly likely that IPA is not inert under the prevailing reaction conditions and that the product oils contain product derived from IPA. To gain insights in this possibility, the liquid reaction product of the blank reaction (Table , expt 3) was also analyzed in detail.…”

“…These products are all likely to originate from IPA through a reaction pathway provided in Scheme . It involves the initial dehydrogenation of IPA to acetone, followed by aldol condenation to form diacetylacetone (DA). DA may subsequently dehydrate into mestityl oxide (MO), which is then catalytically hydrogenated to give MIBK.…”

“…nanoparticles have been widely used as the catalyst support in organic transformation [16]. Our previous achievements in the synthesis of different organic synthons of important biological activities utilizing different nanosized solid heterogeneous catalysts under green protocol [17][18][19][20][21][22] revealed that exploring efficient, sustainable and green catalyst is crucial to achieve green sustainable perspectives. To attain our goal, natural biopolymer supported heterogeneous nano-catalysts that have been utilized in recent years [23,24], was selected to be a catalyst support.…”

Chitosan decorated copper nanoparticles catalysts (CSCuNPs) were synthesized via reduction methods utilizing green protocol. The CSCuNPs catalysts were tested for the synthesis of quinoline derivatives utilizing one-pot multicomponent reaction (MCR) under ultrasonic irradiation. The best catalyst (Cu-CS-NPs) that provided good conversion reaction yield and high turnover frequency (TOF) was characterized using FTIR, TGA, XRD, TEM and XPS techniques. Generalization of the scope of the proposed catalytic process was studied using different aldehydes. Excellent products yield and high TOF in even shorter reaction time (~5 min) was attained. Recyclability performance of the catalyst over five times re-use without detectable loss in product yield was recorded. The current method is green process utilizing environmentally benign catalyst and considered to be promising sustainable protocol for the synthesis of fine chemicals.

Chitosan decorated copper nanoparticles catalysts (CSCuNPs) were synthesized via reduction methods utilizing green protocol. The catalytic performance of CSCuNPs were tested for one-pot multicomponent reaction (MCR) using four reactant components: aromatic aldehydes, dimedone, ammonium acetate and ethylcyanoacetate under ultrasonic irradiation. The best catalyst (Cu-CS-NPs) that provided good conversion reaction yield and high turnover frequency (TOF) utilizing a facile and fast ultrasonic process was characterized using FTIR, TGA, XRD, TEM and XPS techniques. Generalization of the scope of the proposed catalytic process was studied using different aldehydes and excellent products yields and high TOF in even shorter reaction time (5 min.) was attained. Recyclability performance of the catalyst over five times re-use without detectable loss in product yield was recorded. The current method is green process utilizing environmentally benign catalyst and considered to be promising sustainable protocol for the synthesis of fine chemicals.
