Introverted Phosphorus-Au Cavitands for Catalytic Use
Schramm, Michael P.,Kanaura, Mao,Ito, Kouhei,Ide, Masataka,Iwasawa, Tetsuo
, p. 813 - 820 (2016)
A preparative synthesis of an inwardly directed phosphoramidite-Au complex is described and a description of some of its catalytic performance. The molecular structure was determined by crystallographic analysis, which disclosed that the phosphoramidite ligand points “out” and places the complexed Au “in”. We investigated its catalytic activities and found that the inwardly directed Au is surrounded by three inert walls that provide new opportunities for supramolecular catalysis and study of reactive intermediates.
Using triethynylphosphine ligands bearing bulky end caps to create a holey catalytic environment: Application to gold(I)-catalyzed alkyne cyclizations
Ochida, Atsuko,Ito, Hideto,Sawamura, Masaya
, p. 16486 - 16487 (2006)
The synthesis, properties and catalytic uses of phosphinoalkynes bearing bulky end caps at the alkyne termini, that is, tris[(triarylsilyl)ethynyl]phosphines are reported. The most salient feature of the new phosphines is the holey molecular shape possess
Metal-ligand-Lewis acid multi-cooperative catalysis: A step forward in the Conia-ene reaction
Clerc, Arnaud,Marelli, Enrico,Adet, Nicolas,Monot, Julien,Martín-Vaca, Blanca,Bourissou, Didier
, p. 435 - 441 (2021)
An original multi-cooperative catalytic approach was developed by combining metal-ligand cooperation and Lewis acid activation. The [(SCS)Pd]2 complex featuring a non-innocent indenediide-based ligand was found to be a very efficient and versatile catalys
General zinc-catalyzed Conia-ene reactions of 1,3-dicarbonyl compounds with alkynes including the classically challenging substrates under neat conditions

supporting information; experimental part, p. 3096 - 3100 (2010/04/24)
A simple, versatile new approach to fourmembered ring to six-membered ring products has been developed by zinc-catalyzed intramolecular Conia-ene reactions of 1,3-dicarbonyl compounds with alkynes. This new route allows a wide range of dicarbonyl compounds, including the classically challenging 1,3-diesters and N,N'-disubstituted 1,3-keto amides, to be used for the Conia-ene reaction with inexpensive zinc chloride (ZnCl2) under neat conditions.
Cyclisation of ω-unsaturated β-dicarbonylcompounds catalyzed by a palladium hydride species
Monteiro,Balme,Gore
, p. 1645 - 1648 (2007/10/02)
When treated with potassium t-butoxide and then with a palladium(0) complex, the title compounds 1, 2, or 9 are smoothly cyclized by an attack of the enolates onto the unsaturation assisted by a palladium(II) species of tBuO-Pd-H type. The formation of a
