1,1,1-Trichloro-3-(1-phenethylamino-ethylidene)-pentane-2,4-dione is spectroscopically and structurally elucidated by means of linear-polarized IR spectroscopy (IR-LD) of oriented solids as a colloidal suspension in nematic liquid crystal. Structural info
A simple protocol for the preparation of β-enamino ketones catalyzed by NbOPO4under solvent free conditions
Wodtke, Felipe,Xavier, Fernando R.,Mendes, Samuel R.,de Oliveira, Alfredo R.M.,Gariani, Rogério A.
, p. 231 - 234 (2017)
A novel application of the highly stable niobium oxide phosphate (NbOPO4) as an efficient catalyst for the synthesis of β-enamino ketones under solvent-free conditions is described. This protocol, exhibits attractive yields, short reaction periods, lower loading of catalyst and high chemoselectivity.

A facile amination of 1,3-dicarbonyl compounds with amines or ammonium salts has been achieved under microwave irradiation in the presence of acidic ionic liquid 1-butyl-3-methylimidazolium hydrogen sulphate. The method has the advantage of solvent free reactions, short reaction time and mild conditions.

A series of aluminum alkyl complexes nacnacRAlMe2 (2a-2h) bearing aliphatic N-substituted β-diketiminate ligands (nacnac RH = N,N′-dialkyl-2-amino-4-iminopent-2-enes), were prepared from the reaction of trialkyl aluminum and the corresponding β-diketimines. All these aluminum complexes were characterized by NMR, elemental analysis and HRMS spectroscopy. The molecular structures of complexes 2a, 2c and 2h were confirmed by single-crystal X-ray diffraction. These aluminum alkyl complexes show notable activity towards the ring-opening polymerization of ε-caprolactone in the absence and presence of alcohol, and the resulting polymers have narrow molecular weight distributions.

experimental part, p. 3047 - 3053 (2010/11/04)
A variety of β-enamino esters and β-enaminones can be synthesized by the reaction of 1,3-dicarbonyl compounds and various primary amines in the presence of catalytic amount of ferric(III) ammonium nitrate at room temperature. This method is simple, requires short reaction times, high yield and the reaction proceeds under solvent-free conditions.

Li, Geng-Chen
, p. 696 - 698 (2008/09/20)
A convenient eco-friendly procedure has been developed for the synthesis of β-enaminones and β-enamino esters by reacting 1,3-dicarbonyl compounds with amines in the presence of catalytic amounts of phosphotungstic acid (H3PW12O40,1 mol%). The reaction proceeds smoothly at room temperature under solvent-free conditions and gives the corresponding β-enamino compounds in high to excellent yields.
