An X-ray diffraction study has been carried out of the photochemically inactive 1-benzoyl-2-(N-acetyl-N-phenylamino)ethylene C17H15NO2 (diffractometer, λCuKα radiation, 1110 independent reflections, direct method, full-matrix least-squares method, R = 0.037).The crystals are monoclinic, a = 8.268(8), b = 9.703(4), c = 17.473(6) Angstroem, γ = 83 deg 20'(3'), space group P21/b, Z = 4.The possible reasons for the photostability of the compound related to the absence of steric strains in the molecule are discussed.

We have developed an iron-catalyzed direct olefination for enaminone synthesis, with saturated ketones as a source of olefins. This direct ketone β-functionalization reaction has readily available starting materials and a wide range of substrates and requires mild reaction conditions.
Silver(i)/base-promoted propargyl alcohol-controlled regio- or stereoselective synthesis of furan-3-carboxamides and (Z)-enaminones

A novel and facile regioselective synthesis of furan-3-carboxamides by a silver(i)/base-promoted reaction of propargyl alcohol with 3-oxo amides has been demonstrated. This one-pot protocol provides a rapid synthetic approach to diverse trisubstituted furan-3-carboxamides via cascade nucleophilic addition, intramolecular cyclization, elimination, and isomerization reactions. Employing a substituted propargyl alcohol, (Z)-enaminones have been obtained with high stereoselectivities by a Ag2CO3-promoted reaction starting from 3-oxo amides via C-N bond cleavage.

Conjugate Addition of 3-Buytn-2-one to Anilines in Ethanol: Alkene Geometric Insights through in Situ FTIR Monitoring
Chisholm, David R.,Valentine, Roy,Pohl, Ehmke,Whiting, Andrew
, p. 7557 - 7565 (2016/09/09)
A convenient, mild and effective conjugate addition of 3-butyn-2-one to a variety of anilines in ethanol is reported. The reaction was monitored and characterized through in situ FTIR, and the dynamics of the facile E/Z alkene geometry interconversion of the resultant aniline-derived enaminones was explored through NMR, FTIR and X-ray crystallography. A straightforward purification protocol that employs direct Kugelrohr distillation was identified, and the method was further extended to other amines and ynones, allowing rapid access to these interesting compounds.

A facile general green synthetic route to 3-(alkyl/aralkyl/aryl)amino-1- arylprop-2-en-1-ones in excellent yields has been developed by reacting formylated acetophenones with primary amines assisted by KHSO4 in water.
Ruthenium complexes of electronically coupled cyclopentadienone ligands - Catalysts for transformations of propargyl alcohols
Haak, Edgar
, p. 2815 - 2824 (2008/03/13)
A series of donor- and acceptor-substituted ruthenium cyclopentadienone complexes were synthesized and their catalytic activities towards propargyl alcohols focused on amination reactions have been investigated. It is shown that the substituents of the cyclopentadienone ligand determine the mode of activation of propargyl alcohols by these complexes leading to different central intermediates in catalytic cycles. Catalytic transformations of propargyl alcohols to α- or β-amino ketones, enamino ketones, α,β-unsaturated imines, ketones, alkenes and conjugated enynes could be achieved.
