A three-component, Strecker reaction of a series of aldehydes or ketones, amines, and trimethylsilyl cyanide for the synthesis of α-aminonitriles in the presence of a catalytic amount of a magnetic solid sulfonic acid catalyst, Fe3O4@SiO2@Me&Et-PhSO3H under solvent-free conditions have been investigated. This catalyst, with a combination of hydrophobicity and acidity on the Fe3O 4@SiO2 core-shell of the magnetic nanobeads, as well as its water-resistant property, enabled easy mass transfer and catalytic activity in the Strecker reaction. The catalyst was easily separated by an external magnet and the recovered catalyst was reused in 6 successive reaction cycles without any significant loss of activity.
Highly efficient and convenient Strecker reaction of carbonyl compounds and amines with TMSCN catalyzed by MCM-41 anchored sulfonic acid as a recoverable catalyst

experimental part, p. 922 - 930 (2012/02/01)
MCM-41 anchored sulfonic acid (MCM-41-SO3H) was found to be a highly efficient and recoverable heterogeneous catalyst for the three-component Strecker reaction of aldehydes or ketones and diverse amines using trimethylsilyl cyanide (TMSCN) to afford the corresponding α-amino nitriles under mild conditions in high to quantitative yields. The simple experimental procedure along with easy recovery and reusability of the catalyst has led to development of a clean and environmentally friendly approach for the synthesis of α-amino nitriles.
Organometallic hollow spheres bearing bis(N-Heterocyclic carbene)-palladium species: Catalytic application in three-component Strecker reactions
Choi, Jaewon,Yang, Hye Yun,Kim, Hae Jin,Son, Seung Uk
scheme or table, p. 7718 - 7722 (2010/12/25)
Hollow-sphere catalysts were prepared by means of 3D network formation between a tetraimidazolium building block and palladium acetate. The bis(N-heterocyclic carbene)-palladium species that were concomitantly formed during growth of the hollow spheres sh
N-HETEROCYCLIC CARBENE-AMIDO PALLADIUM(II) CATALYSTS AND METHOD OF USE THEREOF

Page/Page column 9; 10, (2010/03/02)
A new N-heterocyclic catalyst system which contains N-heterocyclic carbene and amido as ligands, which are strongly bound to a palladium metal. Another heteroatom functionality can be used as a third ligand L. The NHC-amidate ligand system is unique in structure, and shows excellent reactivities in a number of chemical reactions. The chemical reactions include carbon-carbon and carbon-heteroatom (oxygen and nitrogen) bond formations, and oxidation reactions of saturated carbon chemicals via C—H activation.
Synthesis and reactions of 4-hydroxy-2(1H)-pyridones with thienyl and pyridyl substituents in position 6 starting with azomethines and malonates
Schnell, Barbara
, p. 541 - 548 (2007/10/03)
The reaction of 4 with substituted diethyl malonates 5a, or 'magic malonates' (bis-2,4,6-trichlorophenylmalonates 5b) leads to 4-hydroxy-2(1H)- pyridones 6. The azomethines 4 are prepared via the Strecker compounds 3 starting with methyl ketones 1, anilines, and potassium cyanide. Chlorination of pyridones 6 with sulfuryl chloride leads to compounds 7 while nitration gives 9.
