PCP-Bis(phosphinite) pincer complexes: new homogeneous catalysts for α-arylation of ketones
Churruca, Fátima,SanMartin, Raul,Tellitu, Imanol,Domínguez, Esther
, p. 3233 - 3237 (2006)
Two new p-alkoxycarbonylated palladium bis(phosphinite) PCP pincer complexes are easily prepared and for the first time evaluated as homogeneous catalysts in α-arylation of ketone enolates. Apart from the total absence of phenyl-aryl exchange by-products and significantly low catalyst loadings, the general α-arylation protocols described in this letter feature not only a broad applicability to a range of ketones and aryl bromides with marked electronic and steric differences but also the possibility to generate mono-diarylated products.

1,2-Indandione reacts efficiently with arenes to give 2,2-diaryl-1- indanones by the hydroxyalkylation reaction. The Bronsted superacid CF3SO3H (triflic acid) is an effective catalyst for these condensation reactions. The requisite 1
Carbopalladation of nitriles: Synthesis of benzocyclic ketones and cyclopentenones via Pd-catalyzed cyclization of ω-(2-iodoaryl)alkanenitriles and related compounds

An efficient procedure for the synthesis of 2,2-disubstituted benzocyclic ketones by intramolecular carbopalladation of nitriles has been developed. The cyclization of substituted 3-(2-iodoaryl)-propanenitriles affords indanones in high yields. The reaction is compatible with a wide variety of functional groups. This methodology has been extended to the synthesis of tetralones and cyclopentenones.

Direct α-arylation of ketones: The reaction of cyclic ketone enolates with diphenyliodonium triflate
Ryan, John H.,Stang, Peter J.
, p. 5061 - 5064 (2007/10/03)
Diphenyliodonium triflate 1a reacts with the lithium enolates of cyclic ketones 2 (ring size = 5 - 8), in the presence of stoichiometric quantities of copper cyanide, to afford the corresponding α-phenylated ketones 3 or α,α'-diphenylated ketones 4.
