P2O5/SiO2 (30% w/w) was applied as an efficient, heterogeneous, and reusable catalyst for the synthesis of β-enaminones. The reactions were rapidly completed at 80°C under solvent-free conditions and products were obtained in good to excellent yields. Copyright Taylor & Francis Group, LLC.

scheme or table, p. 217 - 221 (2009/04/06)
Enamination of a wide variety of primary amines was successfully described with excellent chemoselectivity in the presence of catalytic amounts of β-cyclodextrin in water under mild conditions. Aliphatic amines also reacted efficiently to produce the corresponding enaminones.

Enamination of a wide variety of primary amines was successfully carried out in the presence of catalytic amounts of bismuth(III) trifluoroacetate immobilized on molten tetrabutylammonium bromide as "green" media under mild conditions. This new system of the catalyst is recyclable and reusable. Generally, the results of the reaction in tetrabutylammonium bromide is better than the previously obtained results in water because of their yields and reaction times.
A mild, efficient and environmentally friendly method for the regio- and chemoselective synthesis of enaminones using Bi(TFA)3 as a reusable catalyst in aqueous media
Khosropour, Ahmad R.,Khodaei, Mohammad M.,Kookhazadeh, Mehdi
, p. 1725 - 1728 (2007/10/03)
Bismuth(III) trifluoroacetate has been found to be an extremely efficient catalyst for the preparation of β-enaminones in water. In addition, by employing this catalyst, high regio- and chemoselective enamination of carbonyl compounds was achieved.
Volatility Studies of Metal Chelates. V. Stability and Volatility of Transition Metal Chelates of Tetradentate Schiff Bases
Dilli, Sergio,Patsalides, Emilios
, p. 1579 - 1591 (2007/10/02)
A study of the effect of substituent groups on the thermal stability and volatility of 15 tetradentate β-keto enamines and various copper(II), nickel(II), palladium(II), cobalt(II), and oxovanadium(IV) derivatives has been made by employing simultaneous t
