Intramolecular C-O bond forming reactions of aryl 2-bromobenzyl ketones lead to benzo[b]furans. The cyclizations can be catalyzed by 10 mol% of iron trichloride (of 98% or of 99.995% purity) or sub-mol% quantities of copper(II) chloride (of 99.995% purity

Enolates derived from α-(ortho-haloaryl)-substituted ketones undergo palladium-catalysed C-O bond formation to deliver benzofuran products in good yield. A catalyst generated from Pd2(dba)3 and the ligand DPEphos effects the key bond

(Chemical Equation Presented) A single tandem operation allows rapid access to a variety of substituted N-functionalized indoles. The nitrogen atom of the indole nucleus is incorporated through Pd-catalyzed aryl and alkenyl C-N bond-forming reactions (see scheme; dba = dibenzylideneacetone). Amine, aniline, amide, carbamate, and sulfonamide functional groups can be introduced efficiently.
Palladium-catalyzed intramolecular O-arylation of enolates: Application to benzo[6]furan synthesis

, p. 4755 - 4757 (2007/10/03)
(Chemical Equation Presented) A catalyst generated from Pd 2(dba)3 and the ligand DPEphos effects intramolecular C-O bond formation between enolates and aryl halides in the conversion of 1-(2-haloaryl)ketones directly into the corres
