Corrigendum to “A novel thiocarbamide functionalized graphene oxide supported bimetallic monodisperse Rh-Pt nanoparticles (RhPt/TC@GO NPs) for Knoevenagel condensation of aryl aldehydes together with malononitrile” [Appl. Catal. B: Environ. 225 (2018) 148–153]

Is a Catalyst Always Needed? The Case of the Knoevenagel Reaction with Malononitrile

“…Palladium‐nickel nanoparticles on graphene oxide (PdNi@GO) was used in water/ethanol at rt (entries 16–17) [50] . A bimetallic catalyst based on monodisperse Rh‐Pt nanoparticles onto thiocarbamide functionalized graphene oxide (RhPt/TC@GO NPs) was used in short reaction times in water/methanol at room temperature (entries 18–19) [9a] . The blank test with 4‐chlorobenzaldehyde under the adopted condition gave only traces of the product.…”

Cerium immobilized carbon nitride: A proficient and recyclable catalyst to construct carbon–carbon double bonds in water

“…[11] One such approach is the condensation between a carbonyl compound and an active methylene moiety-possessing molecule with the utilization of a wide variety of catalysts including mesoporous materials, metal-organic frameworks, bimetallic, mixed oxide, graphitic carbon nitride, and deep eutectic solvents. [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31] Further, hazardous solvents including tetrahydrofuran, [32,33] dimethyl formamide, [34] alcohols, [35,36] dioxane, [37] toluene, [38] acetonitrile, [39] and dichloromethane [40] have often been used to effect this carbon-carbon bond construction. [41][42][43][44][45][46][47] For instance, Hassan et al [41] showed the capacity of amino-grafted graphene oxide-Fe 3 O 4 in tetrahydrofuran at 50 C, Markad et al [44] exposed the performance of amidefunctionalized 2D coordination polymer (involving a bis-pyridylmethyldiaminobutane diacetamide) in methanol, Taher et al [45] revealed the amine-functionalized metal-organic framework in DMF, Zhong et al [46] discovered the utility of bifunctional mesoporous carbon nitride in toluene at 80 C under ...…”
