Silica supported Fe(HSO4)3 as an efficient, heterogeneous and recyclable catalyst for synthesis of β-enaminones and β-enamino esters

A series of β-substituted enaminones were prepared through the one-pot reaction of β-dicarbonyl compounds with various amines in the presence of silica ferric hydrogensulfate under solvent free conditions at room temperature. The reactions proceed smoothl

A Reusable CNT-Supported Single-Atom Iron Catalyst for the Highly Efficient Synthesis of C?N Bonds

C?N bond formation is regarded as a very useful and fundamental reaction for the synthesis of nitrogen-containing molecules in both organic and pharmaceutical chemistry. Noble-metal and homogeneous catalysts have frequently been used for C?N bond formatio

Solvent-free synthesis of β-enamino ketones and esters catalysed by recyclable iron(III) triflate

A novel application of highly stable Fe(OTf)3 as an efficient catalyst for the synthesis of a variety of β-enamino ketones and esters under solvent-free conditions is described. Notably, this protocol of a "green synthesis", which produced β-enamino ketones and esters by the reaction of a variety of β-dicarbonyl compounds and primary amines, exhibits attractive properties including high yields, short reaction periods, lower loading of catalyst and chemo- and regio-selectivity. In addition, the catalyst was easily recovered from the reaction system and readily reused with minimal loss of activity.

Formic acid: A low-cost, mild, ecofriendly, and highly efficient catalyst for the rapid synthesis of β-enaminones

β-Enaminones have been synthesized by the condensation reaction of b-diketones with various anilines in the presence of a catalytic amount of formic acid, mild and highly efficient acid catalyst in methanol. These condensation reactions proceed smoothly in short reaction times with near-quantitative yields. Copyright

Zinc triflate catalysed synthesis of β-enamino ketones(esters) under solvent-free conditions

An efficient and mild procedure is described for the synthesis of a series of β-enamino ketones(esters) from 1,3-dicarbonyl compounds and aliphatic and aromatic amines using zinc triflate as the catalyst.

Ionic liquid promoted simple and efficient synthesis of β-enamino esters and β-enaminones from 1,3-dicarbonyl compounds - One-pot, three-component reaction for the synthesis of substituted pyridines

A facile enamination of 1,3-dicarbonyl compounds with amines has been developed that affords good to excellent yields of β-enamino esters and β-enaminones using Bronsted acidic ionic liquid 1-methylimidazolium trifluoroacetate ([Hmim]+Tfa-) at room temperature. This methodology has been extended for the synthesis of substituted pyridines in excellent yield by a one-pot, three-component reaction of 1,3-dicarbonyl compounds, ammonium acetate, and alkynone in the presence of [Hmim] +Tfa-.

Synthesis, NMR and X-ray characterisation of 6-substituted 4-amino-5-aryldiazenyl-1-arylpyridazinium salts

A new simple method has been used to prepare 6-substituted 4-(subst. amino)-5-aryldiazenyl-1-arylpyridazinium salts from N-methyl- or N-aryl-3-amino-1-phenylbut-2-en-1-ones and 4-aminopent-3-en-2-ones and substituted benzenediazonium tetrafluoroborates or hexafluorophosphates. The structure of selected derivatives was studied by means of 15N NMR spectra and X-ray.
